Hello Everyone, With the days getting shorter, I'm going to work in the morning when it's dark. I back into my space at work and it is really hard to see, my backup lamps don't put off a lot of light. I still have the incandescent bulbs in my 2018 GMC Sierra 2500HD SLT, has anybody upgraded or retrofitted to LED's ? I know with some to the older systems and LED replacement bulbs you had to install resistors, do you still need to do this? You can purchase just about anything in LED and they are they won't break the bank these days. Has anybody performed this upgrade, if so what brand of LED's are you utilizing? Are you only retrofitting the Reverse lamp bulbs? What about the Turn/Brake and Running lamp bulbs, if you retrofitted them to LED, would they be too bright? Interested in what others are doing.

I have a 2007 GMC Sierra with a Duramax LBZ. My fog lights will not come on with the push button. I have checked all the relevant fuses. I removed the under hood relay and jumped from 30 to 87 and both fog lights come on but the indicator on the button does not. One of the other terminals (85 or 86) has full voltage on it. The other has around 10 volts. I read that the BCM (body control module) supplies a ground to this relay. Aside from replacing the BCM, does anyone have helpful advice? Thanks in advance
