921/T15: Morimoto XB LED
BACK THAT THING UP! Morimoto's new XB 921 LED Bulbs are designed just for reverse lights! Utilizing a big boy CREE XB-D LED emitted through a proprietary Kuria Optic clear glass lens, you'll be able to actually see objects as you back up!
6061 AL: The extruded aluminum heatsink features a smooth 6-Fin design and is finished in a gorgeous graphite color to compliment other Morimoto LED bulbs. This bulb feels rock solid in your hands--no room for any chintzy cheap stuff here!
BEEFY BASE The white ceramic base handles heat much better than cheap plastic bases, and even though they're only lit up for a brief period of time while you're in reverse and probably wont get all that hot - why risk it? The printed "XB LED" graphics are a nice touch too.
CREE LED A single XB-D 5500K emitter blasts a very color-neutral white light through the mini projector lens. The output is end-firing like most 921 sockets require, meaning the light coming out of the bulb is aimed directly backward where you want it most!
