Vanquish vs Phillips Led 921

[adventurenali92]

I have Phillips 921 LEDs as my reverse bulbs until I experienced failure of both taillights. When they replaced them they took my bulbs. I have some concern that using an aftermarket bulb could be related to the failure and we all know how expensive the lights are. Has anyone had any direct experience comparing Vanquish with the Phillips? Anyone able to chime in on relation to taillight failure?

From what I’ve seen, it seems that gm just made a really crappy tail light on the Yukon’s. And internal electronics are what seem to go bad. So I highly doubt your LED reverse bulbs caused the issue. I’ve had LEDs in my reverse lights for two years now and not had issues with them.
As to vanquish, I personally have not bought anything from them. I’ve seen a lot of negative reviews about their products, and a lot of customers not getting what they actually ordered and not getting any help from the company. The last reply on this thread is the first positive review of vanquish I’ve seen. That aspect would steer me clear of them but that’s up to you to decide.
