The 55w H4 Halogen bulbs are awesome. They are not compatible for our old Hondas because they draw too much power which is why we replaced them in our buckets! However, if you have a more modern bike or something with four wheels these will work great. While you are perusing to upgrade your old Honda, take advantage of these H4 halogen bulbs that are priced to move and improve your other rides. These ain't ya mama's nite lights, get you some of these big boys.
