I'm asking the same age old question that I never can find the best answer to.. I'm running Delta H4's in my YJ and I have a ARB M002 coming in the mail right now. I'm gonna wire it up and check out the output this weekend but I have a feeling that the 60/55 watt xenons that are in there aren't gonna have the output that I'm looking for. I dont want HID's nor do I want this thread to be about them. I was considering the Fatboy bulbs but I'm not sure what would work the best for my setup. Does anyone have suggestions for what would work well?
