Stock HID 2018 Tahoe ??

[cmatt]

The bulb mounting tabs are most likely different between the projectors (H11 halogen bulb vs. a D3S HID bulb). I don’t know if there are any differences in the projector designs for the two different bulbs.

@Tiki I knew I had these somewhere. You can see the difference in the mounting holes.

Halogen H11


HID


For reference, these are the factory HID bulbs.

@cmatt so SLT have H11 stock as well correct? Aside from the custom harness, how did you address the mounting hole difference? Or did you get the complete headlight assembly?

 

[cmatt]

Yes, that’s correct. I swapped in the complete HID headlamp assemblies.

Fak! I was hoping for a simpler solution. Outside the mounting hole, what's the difference between the housing/reflector?

 

[cmatt]

I know. Nothing is simple these days.

Obviously, the entire headlamp assembly will bolt right in. As for the rest of the projector similarities, I can’t get a good enough look at them while they’re inside the headlamp housing. However, you can see in the photos where the front and rear halves (projector bowl that holds the bulb and lens bracket that holds the lens) are bolted together. I wonder if the front half of the projector that holds the lens is the same for halogen and HID.

Anyone ever opened up a headlight? We need to see what it looks like inside.

There is a simpler solution to swapping in the whole factory HID housing. I bought all an HID kit for our 2017 Yukon SLT from Vanquish Auto. Check them out. They have a quality canbus HID kit and I have been very happy with them. I also bought their 6000k LED high beam and fog light kit. In the pics you can see a clear comparison between the 6000k HID on driver side vs stock halogen on passenger side.

This is with both HID bulbs installed.

And their customer service sucks. Many posts on this site about them.

I can only speak from my experience. I had a good experience with them on both our Yukon and my 06 F250 when I decided to change everything over to LED on it. Not a single problem. Had to leave a message when I called but they always called back within a reasonable timeframe. I don’t know.....maybe they’ve gotten worse since I bought my stuff?

@zkutilek what mounting tabs did the bulbs use?
