So after purchasing my '19 Trail Boss LT with the LED headlights, I realized my wife's '16 Yukon SLT with the halogen bulbs in a projector housing was just horrible and unsafe compared to what I was seeing driving my truck. I guess we were just use to the poor lighting of the low beams on the Yukon it never bothered us until we got my truck. So after researching for a few months, I purchased some H11 GTR Ultra Series 2.0 Leds from Headlight Revolution for $200. I installed them in about 15 minutes as the passenger side took a little longer with the air box in the way. It is literally a night and day difference in the visibility the Yukon has now with LEDs in the stock projector housing. Only problem I had for 2 days was passenger bulb would flicker and then turn off. I would have to manually turn on and off the lights to get them working. Talked to Headlight Revolution, they said get a video of it happening and send for warranty on the bulb. Well, it has not happened again in the last 3 nights driving it around. So until it does it again, I have no video to send them. ANYWAYS, here are a few pics. I can get more if needed.
