LED equivalents are coming out daily for most every incandescent/halogen bulb out there. I've tried a few and so far no problems and favorable results. The much lower amp draw is great, but longevity is an unknown in some cases. Don't think I'm ready yet for an H4 LED substitute bulb packaged in a H4 headlight housing with a reflector designed for a halogen bulb, probably never will be, but will be interested in your findings. :cheers:
