You have to make sure the BCM update that bumps up the the voltage. That is the update where GM tried to appease the the people that purchased the 14/15 model year Sierras.

PIT5374 is what the bulletin number was back in 2015, not sure if it’s changed or not. Included updated volsa bulbs from Germany and a reflash to up the voltage to the bulbs.


Hooksets are free...

When I originally asked the dealer I literally had to bring in print outs of the bulletin as they had no clue, or played dumb. You may have better luck now haha. If anything get the update and ditch the bulbs, they weren’t anything special from what I’ve read, I never had them installed on mine.

I had to do this with the radiator recall. Literally printed out the bulletin for the overcycling t-stat issue so they would replace my radiator under powertrain. This was after they quoted me 800 to replace it. GM made it worth my while.

 

I already have D2S projectors so I’m pretty far beyond their “upgraded bulbs” at this point.

 

Thanks guys
