Hey Guys, I want to upgrade my headlights to Piaa bulbs. Piaa recommeds using H4 for the high beams and H7 for the low beams. Can I use H4 bulbs for both high and low beams?
H7 and H4 are werry diffrent. If you get a H4 attatced instead of a H7 it will give a odd light, proberly less light on the road mor in the eye of others. I say stay in what recomended!
