Just had the new update, lighting still inadequate. Unsuccessful at trying to access/obtain aftermarket bulbs. Would seem no one makes a replacement 9012 bulb. ( at least one that is available in Canada) :nonod:

9011's with some trimming will help.

The 9011 and 9012s I added in my 05 were an improvement over the 100 watt 9005 and 80 watt 9006s I had. Better spread and more even light. I would just do a quick online search and get some Phillips 9011s to try. You likely will not find them in an auto parts store.

I replaced my low beams with a kit from GTR Lighting plug and play style no cutting. They were so good I did my reverse and fog lights. I can say there not cheep! But we all no the good stuff is not cheep and the cheep stuff is not good. We have a dealer here who gives a good warranty with these check them out. GTR Lightning. Com

Best way to solve the lighting issue on the Sierra is to do what I did... Trade it for a Silverado. SIGNIFICANT difference in the headlight wash on the road and into the shoulders. Much better. My headlight aim is off just slightly on the passenger side (I think). I'll ask the dealer to check it next week when it goes back to have the Line-X liner done.

Sierra for Silverado? It ain't happening jack.. The Sierra is a better looking truck. I like my lights and have no problems. With the right bulbs, BCM update, and properly set I find them good enough for me. Plus I don't like headlights as DRL's and much prefer the LED's on my Sierra. You must've took a beating on a trade just to get different headlights. You would've been better off just getting Anzo's if that's the case. I know some who are running the Anzo's and say the projectors works great.

Never said I traded to get different headlights - bad assumption.

Didn't take a beating on the trade at all - bad assumption.

Sierra SLE - DRLs -are- the headlights - bad assumption.

 

I like the front end look of the Sierra better, prefer the red dash lighting of the Sierra over the blue of the Silverado as well. Needed to "change" other features, and there were NO Sierras in the area with the 20% off. Took the big Chevy incentives PLUS a private offer of $1500 and made out just fine.

 

The lights on the Sierra are not "good enough" for me as I live in a very rural area. They are absolutely sub-standard, even after the BCM update and the Vosla bulb swap.

Not a chance of me doing that!

(1) too expensive , I am not Donald Trump

(2) I prefer the Sierra for several reasons ( lighting is the only complaint)

(3) IMHO it is up to GM to step up to the plate and resolve the issue. From the research I have done I find it is not the bulb that is the problem, but the projector assembly. There are NO aftermarket lights that will provide more distant illumination or a better pattern,, All though various manufacturers "Claim" to increase lighting by 30% or more, they are not giving the consumer the real truth. Their bulbs may be a different color and that will have an effect of brightness, but not give you more light on the road, apparently the only thing that will give you more distance is a different style reflector. From consumer reports.org "Manufacturers of high-priced headlight bulbs are touting brighter light and greater visibility down the road, which is alluring for drivers, but are they much different than standard bulbs? We put eight models of premium bulbs to the test to see how bright and how far they shine.

The $20-$80 premium replacement bulbs from GE, Hella, Phillips, PIAA, and Sylvania were tested in our labs and at the track and compared to standard, cheaper bulbs and the factory bulbs in our 2012 Hyundai Accent and Volkswagen Passat test cars. Our tests revealed that the aftermarket replacements generate a whiter light than the basic bulbs, but they didn't help us see farther in the distance. That is because distance is determined by the shape and size of the reflector or lens in the lamp, not the bulb.

If you just like the stronger white light and don't care about better visibility, then premium bulbs are for you. If your headlight lenses are dull and hazy, the reason could be dirt and oxidation, which can easily be fixed by a headlight restoration kit"

I personally intend on being a pain in GM's ass until this is resolved, suggest many more to do the same.

No problems with the radio....yet! Not impressed with On-Star phone, has a difficult time understanding commands, and it always repeats everything. ."calling, using on-start hands free calling" Like I don't know its using On-star hands free calling!

I don't have a lighting issue so I won't be trading for a Silverado. If I did have a lighting issue I'd get a set of Anzo's or add the Morimoto HID reflector kit and not trade for a Silverado to solve the lighting issue. A co-worker had his BCM updated to 14V, added 9005 Sylvania Silver Star Ultra bulbs (slight trimming on one tab) which are 65w instead of 55w. I rode in his truck and the down road and side visibility were substantially improved over stock.

 

DRL's are the headlights on the SLE unless you change them to the SLT lights and add a harness.

Headlights on Silverado are DRL's - no assumption. That's the fact Jack. The 2016 Silverado will have LED's for DRL's but that will probably only be on the LTZ.

 

If you're happy with you're Silverado then so be it and props to you.

Projectors should not come with halogens to begin with in my opinion, they are just too weak of a light.

 

I am trialing these chinese specials plug and play LED lights before I decide to move on any HID kits because I am lazy and HIDs seem like a lot of work and money for ~600 more lumens than these lights in the pic.

 

Have you got the LED bulbs installed yet?

They are better than stock but still a bit weak distance wise. Spread is improved for sure the the colour of the led is superior to the halogen for sure so that also adds to it.

 

Bunch of guys in this thread tried them as well. About page 30 onward

      Transmission Temperature Hitting 220s

      By DustMcGrath · Posted

      @newdude great info, thank you!   So opening the thermal bypass valve early (or all the time) would cause temperature to rise more slowly, but above 194F there would be no difference from normal operation?   It seems like the only practical ways to bring down the peak temperature would be to improve the oil-air heat exchanger in some way or increase fluid capacity?

      I have a trailer lights checker I plugged into the 7 way connector in the bed of my truck that has the 5th wheel/gooseneck hitch. It gave the camera side view with the turn signal on just like having a trailer connected but it disabled the rear bumper sensors. I would rather have the rear sensors working.

      Blazer is all put back together. Another hard-won battle. The 4.3 is not easy to work on in such an archaic and narrow chassis originally designed for an inline 4.   My baffle issue is solved. I returned to the OG junkyard but was ready for a fight. The Blazer I had picked from was stacked on another vehicle so I had no idea how the heck I was going to get myself to working height to pull the front end apart. I had seen an S10 pickup on the ground so I was hoping the part would be the same, AND, I couldn't remember if the S10 still had a front end or not. But I didn't need to worry because it turned out to be my lucky day. The yard had just taken in a '98 Blazer, sitting right up front, on the ground, with room to work around it, and the front end hadn't been hit. The baffle and all the clips were factory perfect. I also scored another good handful of odds/ends and the whole shebang only cost me $20.   Got everything back together and it fired right off, sounds good, runs good. I've got a little coolant drip from a lower water pump bolt (D'OH!!). I did the right thing and snugged it down a little bit, and of course that didn't fix it. Yet again, I will have to soak everything in coolant to drain it down to the water pump, remove the bolt, and attempt to re-seal it. Nothing is easy on this truck. Nothing. But now all the radiator plastics are correct, snug, and fully functional. No more rubbing on the cooling fan. It runs, drives (took it for a 30 mile drive last night), no Check Engine lights, EGR is working, no vacuum leaks. We're getting closer...   The replacement wiper motor arrived yesterday. The tailgate was already disassembled and waiting, so I threw that in. It works! Sort of. Two new issues on the list. While the motor is strong enough and the gears aren't stripped, the wiper is hanging up on the bottom of the rear glass. This is the old style where the lower half folds down like a truck tailgate, and the glass swings up, and they meet in the middle when closed. The glass isn't sitting flush with the tailgate, now that I look at it. No rubber bumpers that I can see for adjusting, so I'll have to look at the hinge adjustment to see if I can correct it. Also, the washer/squirter just dumps fluid underneath the truck. The lines actually run inside on the floor so I'm guessing the tailgate is soaked at the rear trim and the line is disconnected. There's also a drain there....probably for this reason.   The leaky water pump bolt was really disappointing. JUST STOP LEAKING...OMG!!   Replacing the window motor and a rear door speaker are still to do, and then everything will work. I want this to feel like a "good" vehicle worthy of dropping $600 for new tires before I do. That means no leaking first. I hurt, and I'm kind of cranky, so I'll probably take a day of rest and do the water pump again tomorrow.
