Another thing that is important, is HID bulbs are not designed to be installed in a halogen reflector. They should only ever be installed in a projector.
Projectors have a bit of metal to block the from going where it should not.
Halogen reflectors (the stock headlights in all our tahoes/yukons/suburbans) will cause glare no matter what HID you buy for your truck.
You CAN safely put a quality LED in your low beams and not cause glare, as long as you aren't using one that is putting out much higher than stock number of lumens.
Keep in mind, that I am only talking about your low beam headlights.
I don't care what you do with your high beam lights... go crazy and turn the night into day (but don't burn your truck down).
Just please don't blind the other drivers on the road while you are driving around town.
I highly recommend a quality projector retrofit set headlights for our Tahoes and Yukons. I love my Denali clones on my Yukon XL, and they work great with the set of HIDs I got from
@Vanquish Auto .
I'm also running a cheap set of LEDs in my high beams, but with the 4-high mod, it doesn't seem to matter as much.
Ok, my rant is done.
