I have a set of 9" Hella lights with Sylvania Osram 100w Rally bulbs. I have them wired up to come on with my high beams using the Slee aux harness. The bulbs I took out of the Hellas were 100w and I think they will handle the 100w just fine. Would you have any concern about the wiring or alternator or anything else powering the 100w Hellas and the high beams for a extended period of time? I will obviously call Slee, I assume it will be just fine. But I just wanted to see if anyone else runs 100w driving lights.
