Wondering about the huge price disparity between the Hella 2500 Angel eye driving lights and the PIAA 520-540 driving light. The kit for the Hella is about $55 and the kit for the PIAA is $250+! I've read that many have put the Hella on and love them, same true with the 520's. But $200 difference?? Have had PIAA on a motorcycle and they were ok but not that much better than other fog lights I've had in the past. Must be the marketing/markup game?
