The reflector can make it or break it for these types of conversions. The H4 is set up for the Halogen bulb so I don't know how well an LED would work with it. It would be interesting to find out. Harley Davidson still sells the H4 as a replacement for the bikes that use them. I don't think the new ones use that design but they are 7-inch.
