    Has anyone with a Yukon that has performed this upgrade experienced total tail light failure afterwards?

    I have been using these LED lights as my reverse lights in the Yukon and just experiences both of my tail lights go out within days of each other. But when I replaced my LED reverse light back to the stock OEM incandescent bulb, the light still didnt work, then in the morning it started working again. I really dont think the reverse LED bulbs would cause the brake light LED panel to go out, but wanted to get your thoughts.

    You have other problems going on. The LED Reverse Bulbs aren't going to cause that, because as you saw when you replaced the bulb, the Reverse Bulbs are on a completely different Circuit than the Tail Lights themselves.

    This is what I'm using on my '00 Yukon XL with aftermarket tails.

    If you are using stock tail light assemblies, get anything that has a nice clear lens over the reverse lights. With the stock incandescents, you will instantly be able to see so much better behind you. If you get ether of those LEDs that @Cattivo or I linked to (two different kinds of LEDs), it'll make it even better. I was going to get some LED fog lights for the rear until I got these LED reverse lights.

    I have a post on my build thread that shows the difference between incandescents and the LEDs if you are interested.

    If you want to see if how bright the replacement tail lights look with stock incandescent reverse bulbs, I have a video in this post.
