Product Details

921 T15 Xtreme LED: Xtreme LED 921 T15 ceramic LED Replacement bulbs feature a perfectly positioned CREE MHB-A LED emitter to maximize the use of your tail light optics making them a truly functional reverse / back-up LED light upgrade. Alternate "Tower style" 921 T15 LED bulbs create a lot of wasted light and simply won't provide the light coverage needed for reverse light LED applications--brighter isn't better if light isn't going where it needs to go!

Optimal Heat Dissipation: The body of the bulb is made entirely out of ceramic to ensure the bulb can withstand higher environment temperatures--way better then lower priced plastic alternatives. We've also taken the pioneering step of mounting the CREE LED diode right onto the ceramic body to create the highest possible heat dissipation efficiency --they're bright and reliable!

Perfect design

The description says it best: at only 200 lumens these aren't the brightest, but they put the light where it needs to be, in the reflector. Others use "brute force" to illuminate directly from the leds. These leverage a conical reflector on the base and redirect all of the light to the factory reflector. This is especially important with most modern small and shallow reverse light housings/reflectors. I wish they came in a black finish, but color is second to the impressive performance. I use these in a 2013 F150. Works great for these reflectors.

Super bright, easy to install, took my 15yr old maybe 10 minutes. Love the whiter/brighter look to match my other exterior lights from XenonDepot

Easy Upgrade

I was very pleased with this factory upgrade LED conversion bulb. The color is much better than the factory incandescent. I haven't tested for night visibility but I am sure it will be improved with the research I have done.

A little disappointed

Roy Pudiquet  Reviewed: 4/18/2019 2:28:00 am

The quality of the 921 XTR LED is very good, but I just wish it was a little brighter. It is still brighter than my stock bulbs though.

These backup bulbs are a true enhancement over the stock bulbs. Direct swap out!
