Convert your stock H4 motorcycle headlight bulb to a high performanceMOONSMC® LED bulb. Tired of having a hard time seeing what's in front of you at night on those back canyon roads? We are offering a retro fit, plug and play H4 LED headlight which produces 4500 lumens of bright white light. These LED headlights produce no heat, almost 5 times as much light and requires very little power compared to a standard halogen bulb.
