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!
