Mind you that these are the 35W version of the H3 pigtailed halogen bulbs. Although I haven't, other members use the 55W version found everywhere. A suggestion has been made that the light bar be turned off before starting the motorsickle. Why? Seems to help with a possible bulb killing power surge. Take it for what it's worth. Just like oil choices and "Should I replace the sprockets when I replace a chain".
