on VLED's website it shows as 3156. I assume those will work? I want to get the cree with radial for reverse lights.

 

 

Check your damn bulbs. I'm getting tired of repeating myself. The manuals/listings have proven to be wrong in some cases. It takes all of two minutes.

Well my "damn bulbs" do say 3047 on them. But as I said, VLEDs shows 3156 will work. I just want to be sure. Kind of on the analogy of measuring twice and cut once. I also forgot to mention that they are the 7 watt bulbs. And I don't know what the wattage of the current "damn bulbs" are.

What's Jesus have to do with it? I didn't see anywhere on this post saying that 3156 would work in a 3047 socket. Maybe I missed a page? And I am not exactly a "veteran" when it comes to lighting mods. So not everyone is like you folks and very knowledgeable on said subject. Time and patience is a virtue.

Its the same bulb, so the 3156 CREE bulb will work great in your truck. No worries there!

I ordered these from ebay about 3 weeks ago, from China. (NOTE: I didn't order the wrong lights on purpose, I have 3047 but thought all silverados came with 3156)

 

http://www.ebay.com/itm/130626777064?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

 

I got them in and tried to put them in but the base needed to be trimmed to fit the light socket. Thats when I realized I ordered the wrong part. Shipping back to China is not worth it, and I have no other vehicles that these will fit so I grabbed my dremel. I have a plastic cutting wheel attachment for it so I put it on there and stuck the lights in the socket to mark where they needed to be clearanced. I cut up one to fit, it only took 4 lines up the plastic part to make them fit. But they still didnt work when I put them in the truck.

 

Thinking I got a dud, I grabbed a 9volt battery and the thing worked with it. So I thought then that I needed to reverse the polarity of the 9 volt to match the truck, thinking that was why they werent firing in the truck. But they fired from the 9volt either way. I went back out to the truck and bent the leads in the opposite direction just to try it, and it worked!

 

So I clearanced the other bulb with my dremel and bent the leads the opposite direction and it worked too! I tested them tonite after dark and they are SUPER BRIGHT! I even pulled under an outdoor light and the backup lights were far brighter than the pole mounted light.

 

Sorry for the long post but I figured I might save someone else some money, and trouble if they ordered some cheapies from ebay!

I have had mine in for over two years with no problems. 2010 1500 Silverado Crewcab, the bulbs were 921s and are very bright. I just got the focused CREEs 5W at a local ricer shop for $20 bucks and tested them in the parking lot because they wanted to see them as well. Now all I need is a dash switch so I can flash them ar tailgaters!!!

      MPG at 600 miles

      By Chuck FB · Posted

      I would have to read back to get a better picture in my mind of some of the other comments and what they were using for a driving scenario they based the fuel mileage off of. That is why the fuel mileage conversation is extremely difficult to make fair comparisons from. If I was to be living in town and only driving around town, light to light and some longer stretches that doesn't have a light every block, and the usual stop at a grocery store and the bank and so on and so forth, my fuel mileage even during the summer time would be so bad with my truck I don't even want to know how bad it would be !. Then add in winter time and idling to warm it up to clear the windows and driving through snowy streets etc, large heavy trucks with gas engines have NEVER been worth crap for fuel mileage and why some little pot licker of a car with wheelbarrow tires and a 1300 cc four cylinder non turbo engine was the ticket to using a mere fraction of the fuel over a full size pickup.    By the way my truck has the 34" tires as its a HC but not the BFG KO3 tires ( that was an option for my truck but the sales guy couldn't figure out what the tires actually were so that never got on the order until it was too late to change the truck order ). So what fuel mileage your getting actually sounds good for "town driving" and with my truck when I go to town the fuel mileage keeps increasing as I get closer to town because it takes quite a while to get the driveline oils warmed up ( and why it always shows better fuel mileage on the return trip from town because its already warmed up ) but once I am in town that fuel mileage average just keeps dropping the more I mess around town and then has to recover back to something reasonable again by the time I get home for an over all average.    I'd be curious what your sticker says for the factory weight of your truck, mine is close around that 7700 lb due to the options it has. But anyway the long and short is, vehicle weight, higher rolling resistance heavy tires and a hefty driveline and a relatively large gas engine make for crap fuel mileage in stop and go scenarios, all one can do is drive it easy off the line at each stop and as my dad had said over the years, drive like a raw egg is under your foot and that's the best one can do. Years back with a carbed engine and if the carb was getting a bit out of tune etc as would the ignition system, the fuel mileage on pickups with larger engines was just awful compared to what your getting. We pay the fuel price penalty for driving HD trucks over some little vehicle, that is the reality.

      We had two Toyota’s with that engine in the mid 80s. We had 50 gallon fuel tanks, a toolbox full of tools, an air compressor and assorted parts for our equipment. We beat those up and down pipeline ROWs until we started buying diesel trucks. Then they became parts runners and first vehicles for our teenagers first cars. Our shop Forman wrecked them both two years apart when we hired him out of high school as an apprentice. Good thing he’s an excellent mechanic. It took awhile before he could be called a good driver.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      I have a 2025 GMC Canyon Denali.   On a trip recently the engine failed.  The dealership diagnosed a bent valve and says there is a service bulletin that indicates to 'relace the engine'.  The truck only has about 14K miles and is under warranty.   The failure occurred 5/11/2026.   So far I have worked with GM Customer Assistance and Roadside Assistance.  Evidently no engines are available and nobody will offer a date when a new one will be.   Coming up on two months with no repair or timeline and no loaner from the dealership.   GMC Customer Assistance is 'ghosting' me and keeps closing the cases I've opened with no resolution.   Hoping someone can help me on how to escalate this issue.
