Dual LED module - only for super-SUPER bright requirements! This module has 2Watts of Solid State Illumination power. Don't confuse this with anything else on the market. THIS IS BRIGHT! (RayBans not included**) For normal applications 1Watt will be enough, but if you need the brightest SolidStateRacing light source available to mankind - this is for you! As used on the GLPK 24HR Racing Viper - so they could see it from the other end of the main straight....... need we say more? :)
