Looking to upgrade your stock filament, old school bulbs to these Mega LEDs? We recommend it! These are the brightest 1157 LED bulbs on the market! So bright, that they have a tiny fan built into the bulb and aluminum heat sinks to keep it cool. These also use less voltage than a standard 12v LED bulb, even with it's built in fan! Another cool feature is the internal LED driver has over heating and over current protection. The good stuff!
THESE ARE FOR DC SYSTEMS ONLY! AC WILL KILL THE UNIT.
If your taillight (not brake light) doesn’t light up until the bike is started, it is AC power, and this bulb will not work. If the taillight and brake light will light up with the key on and the engine NOT started, this will work.
