relays for running high intensity h4's?

[willett]

Hi guys,

I upgraded to h4's a couple years ago, but the bulbs in there are pretty crappy. I was thinking about upgrading to some better bulbs but have a friend who did the same thing and ended up frying 3 headlight switches before going back to crappy bulbs.

I was thinking of just using a couple 12v/30A bosch 5 prongers. does anyone see a problem with this? should I run a single relay for both sides, or a seperate relay for each light. I can't really see 2 headlights pushing 30A.

I'm running round headlights (pre-80 style)

as well, who makes a bright h4?
