DIY: Make 2015-2017 LS/LT headlights operate like a LTZ headlight (LED as DRL vice low beams)

Can you give me the info on those fender flares?

Those are EGR 1 inch Fender Flares they fit both tahoes and yukons

Unfortunately there isn’t. There is no control module for the headlights. The LED strip has resistors hardwired into it that step down the voltage.

View attachment 257900 Hey Guys,

so I installed CMatt's latest harness and I'm happy to report it has all functions as described.

Supports:

LED stripe on remote start
Parking Lights
Automatic on when vehicle is in drive

I took it a step further about a year ago by installing the standard 2018 headlights that have the brighter LED light bar, and I have full LED brightness. I'm going to unload a video later to show the results.

great work Matt. This is a photo of my car in drive. It was super sunny so it's harder to see but it's working great

so you got the full brightness at daytime and dimmed at night ?

Theres another option. 2015 model year Just move your headlight switch to parking lights every time you get in. When I was trying to rework all this about 4 years ago this was the only logical way to do it. Honestly once you do it a few times it becomes muscle memory. Yes It also turns on the tail light LEDS which I think are just as important. Headlight DRL's are ridiculous. It used to bother me that my 15's LED's were no where near as bright as the 17+ but then I realized the 17+ were honestly to bright and will most likely burn out faster do to the associated heat.
