Last week I noticed when driving into the garage, that one of my DRL/low beam lights was out. I have a 2015 with the halogen lights, separate high beams. I first read some old posts on here about how to get at them. No problem, I bought a new set of H11 bulbs and went to replace them. I put the new bulb in the driver's side first since it is easier, the new bulb worked. (that old bulb still worked as well). Then I go yank the air box out to get at the passenger side. put new bulb in. After reassembling everything I tested it out by turning on my headlights, and lo and behold, this brand new bulb does not light up. After inspecting the old bulb, I cannot see any sign of it burning out either, no black, nothing broken inside the glass. So my question is, would there be anything I can easily check that would cause this if it is a wiring issue? I'm not terribly worried about it now since I do very little driving after dark and I will be taking my truck in for an inspection right before my 36 month warranty runs out in June. Just wondering if this has been encountered before. I don't want to make a habit of replacing bulbs only to find out they are not the problem. Replacing the passenger side bulb is not fun.

I was wondering if any of you have replaced the cargo and backup bulbs to LED. I have always used Diode Dynamics bulbs in the past because they are great, however I don't want to spend $170 on backup and cargo LED bulbs. I have Diode Dynamic license plate bulbs already because they weren't too high on the price. So if any of you guys replaced them and found bright white LED bulbs that aren't $170 like Diode Dynamics I want to know what brand you went with and where you bought them. Thanks!

I replaced my pass side light bulb about 5 months ago with the same type of halogen bulbs that they come with out of the factory and one day i realized that the same side as before went out. Before that one went out i had a set of after market LED lights. these to be exact https://www.amazon.ca/Lumen-9012HLC-G7-LED-Performance-Bulbs/dp/B01N5Q0TMA i ran those LED's on my truck and they looked great! everything was plug and play they lasted for about 4 months when my pass side bulb gave out on those too. when i took out the bulb to inspect it one of the LED diodes was blown out. I wasn't too surprised by that because sometimes after market parts can be a bit cheaper quality. But when my OEM halogen bulbs went out. thats 3 sets of bulbs in less than 2 years. I am just wondering. Is this bad luck?? Have any of you had this issue before?? if you did what was causing it?? any troubleshooting tips?? I really dont want to keep buying light bulbs every 5 months even the halogen bulbs are a little expensive

Hi. Just wondering if anyone has changed out their front sidemarkers in their 2016-2018 Silverado 1500. Can’t find the access point for it, although I haven’t removed the headlight assemblies to look. Is it not just a standalone socket like the turn signal where you can just turn and pull it out? Thanks.

My issue is a little bit different however none the less an annoying one. So yesterday i bought some led bulbs off amazon to replace the dome lights in my truck, i got them opened them up all looks good and then go to put them in, and as i did they turned on not an issue however they where to small so i have to return them, i put the old one back in and not lights in the dash and dome lights are acting up. So it was the left front one i tried it in and took it back out no others. Now none of the lights turn on by the button inside the truck. (door lights and turning them on by the small switch which turns them all on works just fine. when the door is open i can now turn the light off by pressing the button. now those issues are a little less of a bother to me, however the radio (which still works perfect) now has no lights, same with the driver info center buttons 4wd actuator light and the lights on the steering wheel lights. All the buttons however still work perfect it is just the lights. Any help is much appreciated ! Truck is a 2008 GMC sierra 2500HD SLE Diesel crew cab long box

Looking to upgrade my halogen headlight housing (reflector) light output with some LED headlight bulbs. I understand many people say not to do it as it blinds others, however I rarely drive at night and even then I live in a very rural area with little traffic. Most of the usage with be during the day with the DRL’s. So does anyone have recommendations for what kind of LED bulb I should go with, one that works good in the reflector style headlight housing? Looking for a simple bulb swap, I think you should be able to just swap the bulbs out right?

Review: Sylvania Silverstar/ZEVO LED Exterior Lighting Upgrade Zane Merva Executive Editor, GM-Trucks.com 9/14/15 Are you looking for more visibility and a distinctive look for your vehicle when the sun goes down? We installed replacement SilverStar headlight bulbs to see better at night and ZEVO LED marker bulbs to give Project Sierra a high tech look. Here’s how it went. Product Reviewed Sylvania SilverStar ZXE headlight bulbs (9005/H11) Sylvania ZEVO LED 194 Replacement Bulb Current Retail Cost SilverStar zXe H11: $49 / set SilverStar zXe 9005: $51 / set ZEVO 194 LED: $9.85 x 6 = $59 Total Cost ~ $159 (as of 9/14/2015) Editor's Note: This product was provided at no cost for the purposes of a review. We only publish our honest opinions and give no consideration for the gratis product. What are they? Replacement headlight and marker light bulbs that shine brighter and with a whiter color temperature than stock. The LED bulbs will also never need replaced. Tested On 2011 GMC Sierra All-Terrain Extended Cab SLT SilverStar zXe Headlight Bulbs The SilverStar zXe bulbs are Sylvania’s premium headlight bulbs. Sold in pairs, our Sierra takes H11 for the low beams and 9005 type bulbs for the high beams. SilverStar zXe bulbs are supposed to be the brightest whitest and most "Xenon like" bulbs that Sylvania offers. They provide the bright daylight colored light closer in the spectrum to HID systems without going over the top and having a fake blue tint that only serves to annoy oncoming traffic. Updated: Sylvania has clarified to us that the SilverStar Ultra is the brightest downroad bulb, while zXe bulbs have the highest/whitest color temperature. Installation is as easy as replacing any other headlight bulb. We had the best results on our 2011 using small hands and removing the air filter assembly. ZEVO LED Marker Bulbs Our trucks have around a half dozen mini-bulbs used around the exterior as marker lights. In some new vehicles, these bulbs are now LED. LED's bulbs are brighter, have a high-tech look, and never burn out. Our Sierra came from the factory with 194-sized incandescent marker bulbs that give off a dim yellow light. Even the rear license plate lighting used two of these little outdated bulbs. Thankfully replacing all of them is very easy. Our truck has two 194 bulbs in the headlights, two in the tail lights, and two to illuminate the rear plate at night. We started in the rear and removed the tail light housings using a Phillips head screwdriver. The license plate bulb housings pop out by squeezing a few tabs located behind the bumper. The four bulbs in the rear took under 15 minutes to swap out. The headlight marker bulbs are slightly harder to get to. They reside on the side of the headlight housing, tucked tightly in the front fenders. We used a pair of needle nose pliers to very carefully remove and replace the bulbs up front. Stock vs Sylvania The stock headlight bulbs (left in each photo) vs the SilverStar zXe bulbs (right in each photo). The Sylvania bulbs have a blue tint that can only be seen during the day. That blue tint on the bulbs translates to a slight blue hue in the headlight housing during the day. At night the blue tint isn't apparent. The stock 194 marker light and license plate bulbs are light and fragile. The ZEVO led replacements are sturdy and feel heavier duty. The right/driver side headlight is still stock. The left/passenger side is a SilverStar zXe bulb. The stock halogen bulb light looks yellow and dimmer in comparison. Replacing the 194 marker light bulb in each tail light is a quick job. The reward is a significantly brighter 6000k white light. Stock on left, ZEVO LED on right. The LED bulbs are so much brighter that you can see the light spilling over into the lower part of the taillight. At first we thought this might be a problem but ending up deciding we liked the more aftermarket look it gave our truck. Up close, it's even more obvious that the rear tail lamps benefit from the brighter ZEVO LED bulbs. The stock marker lights are almost unnoticeable. The LED bulbs are unmistakable. The result is the most dramatic when illuminating the rear license plate. The stock 194 bulb(left photo) is yellow and dim. The Sylvania ZEVO LED bulb is much brighter and gives the exterior a better overall appearance. Side by side, it's easy to see the ZEVO LED bulb (left) is a big upgrade in brightness from the stock bulb(right). Since LED's never burn out, you'll most likely never have to replace them again. Conclusion We replaced 10 bulbs on our 2011 Sierra during this lighting makeover. We began enjoying the results the first night and we noticed the difference immediately. Just by looking at the photos above, we’re sure you can too, and that says a lot considering it is very hard to photograph the lights in a way that accurately represents them in real life. The biggest reason that someone would want to buy SilverStar zXe bulbs is for the exterior look they give your vehicle. Sure, the whiter color temperature light is easier on the eyes when driving at night. We'd even go as far to say that we could see the road better because of this. However, in our test, there was not much discernible difference in overall brightness over stock. After all, they both use the same wattage and the same reflective housing. Sylvania offers the SilverStar Ultra line of bulbs for enthusiasts who value brightness over color temperature. In other words, don't expect this upgrade to be as bright as a HID upgrade which adds extra power to the lights. Where SilverStar zXe bulbs really "shine" is that from outside a vehicle, the headlights have a very crisp, almost HID like appearance. The ZEVO LED 194 bulbs are similar in nature. Completely hidden to the driver, LED marker bulbs are great because they will never burn out and they look better and brighter than stock. However, with that said, the brighter corner marker lighting really stands out and we've fallen in love with the modern look. We are looking forward to expanding our exterior makeover to LED tail light and backup bulbs someday in the future. Right now Sylvania doesn't make a set of LED brake light bulbs that are street legal for our Sierra but promises a solution. On the other hand, Sylvania does have backup light bulbs that fit and we're testing them now. We're also excited to share our thoughts of the ZEVO LED Pixelated DRL with you soon.

For those not aware, GM dropped the 3157 sized bulbs in favor of 921's for reverse lights on the 2014's. So my question: which vendors really have the best/brightest LEDs out there??? My DDM's were dimmer than the stick bulbs. I've heard great things about V-LED's Triton LEDs but they don't make a 921.

Has anyone ever successfully crammed these bad boys into the stock rectangle fog lights for a '14 silverado? https://www.amazon.com/OPT7-Fluxbeam-Light-Bulbs-000Lms/dp/B013JCQX4W/ref=sr_1_11?s=automotive&rps=1&ie=UTF8&qid=1507596346&sr=1-11&keywords=5202+LED&refinements=p_72%3A1248861011%2Cp_85%3A2470955011 I'm looking for some fogs that can double as "driving" lights when I want. Not a full replacement, but certainly more than just a little add'l light like stock fogs provide. I like to run with running lights and fogs only a lot. Thanks for the input! E

Hello everyone, This is my first post and I am happy to be here. 'Read many other threads on this forum and I know I'm in good company with ya'll. I searched, and scoured the web (and this forum), and could not find a thread or post that throughly covered the topic of Original Equiptment lighting. Maybe there is a Chilton's or a Haynes Book that covers this? This question popped into my thoughts as I began shopping for an overhead light bar. Of course, lumen, beam flood angle, and beam throw distance were the first specs I poured over, but then I thought about Kº (light temperature in Kelvin degree). It might be cool if this new light added to the truck would match the existing. (I'm pretty happy with the factory lighting choices on my SLE). So I pulled the headlight bulb to find a PHILLIPS hHIR2 LL 55W 9012 LL, Made in Germany. (See photos). When I compare the various replacement bulbs offered by Autozone, the replacements can range from 3000, 3200, 4100, to 4200º Kelvin. This thread might be helpful to others working on interior lighting, or other lighting as well. Anyone out there have professional photography equipment that can meter, or sense color temperature? Are different trucks different temps? Thanks for any info involving measurements, photos, specs, or thoughts that might be helpful to me or to US as a community of owners and technicians. Hopefully this thread could help others too. Thank you.

Hey all, I tried. I searched. Either the search engine on this site is horrible, I can't seem to put in the right key words or there is no dedicated thread in this sub forum for this. One is true, and it's probably not the last one... Looking to replace both my low beams and fogs with solid LED bulb/kits. I've heard BPS has a decent kit. Just looking for the highest quality, best light producing kits that match color. (5000k-6000k) Thanks for the suggestions! Evan

My Brother has a 2016 Colorado, and I would like to get him some LED lights for Christmas to replace his Reverse/backup lights, cargo lights, and license plate lights. I looked around to try and find the light bulb sizes but can't find much info on bulb sizes, I believe the reverse lights are 921, but I am not entirely sure. I would appreciate it if someone could let me know what size bulbs I need. I would hate to order the wrong ones. Thanks in advance. -Carson

Hi Forum, I have been looking for an aftermarket upgrade for the fog lights on my 2014 Silverado. I already have the bulb size but have had no luck in finding any kind of an upgrade, just OEM replacements from Sylvania and Philips, along with some LED options which I am not sure would emit the same beam pattern due to the halogen housing the stock bulb came in. Any suggestions for an aftermarket fog light replacement bulb?

I like how the factory '14+ tail lights look and, of course, OEM light housing durability is typically superior to that of aftermarket components. Anyway, I have considered swapping the factory bulbs to 7444 LEDs (in white or red) and seeing how well they work in the stock housings. I am expecting to need a resistor kit, as I have had to do with past LED conversions on my last truck. Thoughts? Anybody else done this? Thanks for any input!

For some people the low beam headlights can be changed by squeezing your hands in there and getting to them or removing the airbox on the passenger side. The issue with that is that all the other bulbs in that headlight are not accessible. There are many videos but none seemed to be straight forward enough or seemed way to hard so here it is in a few steps. So here goes: Socket sizes are 10 and 7mm First step is removing the 8 fasteners that hold the top cover on. Flat head screw driver works just fine. After removing the plastic cover it will reveal 4 bolts which i believe are 13mm. After removing those remove the 2 bolts on each side that hold the plastic piece below the grill. (they are exposed on the fender well and are 9 or 10mm I think) Next there are 6 clips that hold the grill to the truck. I used channel lock pliers and was easily able to release all the clips. Once you release them, pull them far enough back to have them disconnected from truck. This is where it gets a little tricky but isn't really hard. For me, I grabbed the middle of the painted trim piece and pulled back slightly and worked my way to each side of the truck, releasing it little by little. Once you get to the very ends near the fender well, grab where the bolts were and pull it away from the truck and very slowly work your way around the curve. Because the part is actually pinched in between 2 other parts it takes a little bit of pressure to get it to pull out, and it is also held by a type of clip that doesn't need released, just a little pressure pulling straight out. Don't try to make it come out the first time, I added a little pressure each time I pulled to try to help it work its own way out. The straighter you pull towards you the better, as I said there are clips that hold it. once the 2 sides release you should be able to pull the grill and that trim piece out and set it aside. Once that is out, its easy from here. Each headlights is held in with 3 bolts, 2 of which are easily accessible before you did all that work as they are right on the top. The last bolt is now easily accessible as well. There is a plastic brace looking thing on each corner of the truck with a hole in it. That is your access to the 3rd bolt. Very easy to get to with a short extension. After that one is out the headlight is yours. There are 2 alignment pins on the outside edges of the light so grab toward the fender and pull that side first and then it slides out of the bottom bracket. There is one main big plug that you squeeze to disconnect and then the entire headlight is free from the truck. So after doing what you needed done, reposition the headlight where it goes and install the 3 bolts per light. To reinstall the grill and trim piece set it up as centered as possible and start in the middle. There are good size tabs on the piece that slide into brackets that are on the bumper. So starting in the middle align the tabs and and work to both sides until the corners slide back in. Push the clips back in on the grill, reinstall all bolts and the top cover and youre done. I did not have all the bulbs I needed to do what I wanted to do so I will be doing this again when I have them all and may take pics or a video of it when I do. Any questions let me know. This is how I did it, if you break something its on you if you are changing your grill the steps are identical except you don't have to remove the headlights. all in all its not bad to do, the fear of breaking that trim piece is the worst as it does take some pressure to get it free. I did not use a tool just my hands to pull on it. ​

Question, what is the bulb number for the smaller bulb on the outside of the turn signal? The main signal bulb is 3157 I believe but I can't seem to find any info about the other smaller one and need to replace it.

Does anyone know what size the bulbs under the side mirrors are? When you hit the unlock button on the key remote they light up along with the DRL's. Just can't seem to find them anywhere, and can't find a part number either. Truck is a 2006 Sierra Denali.

I've replaced the bulb and the fuse. I don't know what to do to get the high beam working again.

Hello all, I have a PIAA 4080 Quattro kit I used on my former 2006 silverado. Worked perfectly for years until removed a few months ago when I sold the truck. Everything from the original kit is for sale. I had to cut one or two of the wires for installation and also for removal. I do not have the original box nor instructions but I assume you could get them from internet or PIAA. They still have road dirt on them as I didn't spend half an hour cleaning them just to sell them. Looking to get $100 shipped or best offer, these are really good lights and need to get used by someone. PM or email me if interested. Will be listing on ebay if nobody interested.

2004 2500HD chevrolet. CEL was on but went out while driving. Had the truck at the stealership for some other repairs and they said that the CEL bulb was burnt out but that it could not be repaired, in order to get it on again would mean replacing the whole cluster. Is this true or am I able to remove the cluster and solder in a new bulb?
