2017 Yukon Denali Head Lights are terrible

[battledenali]

Is it just me or are the head lights and even the high beams terrible on these trucks?

I loose track of the guard rail at night and in the rain its 100 times worse, and I lost count of how many pedestrians I have almost hit.

Has anyone done any aftermarket work to fix this issue? My dealer sucks, they pretend to not be able to understand the issue and tell me they adjusted the beams.

The lights on my Denali seem pretty good - Have you verified that they are aimed correctly?

I always have to adjust the headlights on my GM trucks, after 6 Suburban's and 12 Escalade's you just get used to doing it. The dealer will never adjust your headlights high enough. You have HID correct?

My Escalade has leds which are pretty bright but one side was aimed significantly lower than the other. I evened them out

Maybe a stupid question but how do you adjust them?

I have the HID correct. I aim them high, but there is just not enough brightness. Even with the high beams on.

There are torx screws that will adj up/down and left right.

I dropped the truck off today to have 2 pairs of rigid D2 SAE lights installed in the fog light housings. I will post it up when I get it back tomorrow.

Its similar to the setup on a Raptor.

My Denali headlamps are amazing. My 1979 GMC not so much.

My 2017 Denali was terrible when I picked it up. High beams were about as good as low beams should be. The lights were bright, but aimed way to low. Planned to adjust them up, but I added a 1.5" leveling kit the first week. Then they were just fine.
