Significantly boost the output of Morimoto XB Evo or XB Evo Hybrid Headlights with these simple bolt-on power upgrades. Designed as a direct replacement for the standard LED drivers, these are an easy swap on the back of the headlight housings. While standard drivers are under-powering the LED projectors to keep output DOT compliant, these Supercharged drivers unlock the real potential of your headlights, all without any risk to reliability or the warranty. Because of the increase in brightness though, they are not road legal in the US. Off-road use only!
