Funny you should mention this, I was doing some research on replacement bulbs last night. It seems the cheaper bulbs are not adjustable in the housing and may not have a sharp cutoff as those you can adjust,
Potentially blinding oncoming drivers. I started off on headlight revolutions website watched a vid over there and see the sv4 bulb works well in our housings. I looked elsewhere for the sv4 and it looks like headlight revolution stole the bulb design and renamed it according to the guys over at supernova lights. I guess it’s all up to who you believe. The sv4 on supernova has a 4 year warranty. I believe HR warranty’s theirs for 2 years. That’s about as far down the rabbit hole I got last night I’m sure I’ll have some time to dig further today
