Your vintage Kawasaki motorcycle (and other vintage Japanese bikes) restoration will benefit greatly from an H4 headlight conversion. These lights are much brighter than stock halogen bulbs and can work seamlessly without electrical mods. Look to Z1 when it’s time for a KZ1000 H4 halogen replacement bulb. We carry low-watt 55/60W H4 Halogen bulbs that work with no fuss. We also have higher-watt H4 55/100W and 90/100W bulbs, but these bulbs may not be able to be on constantly (especially high beam) without draining the battery. We also stock the rare Honda F-type 30-amp fuse, and 3W instrument panel bulbs (10-pack).
