What Amp Relays Are Needed For H4 Bulbs?
I am putting in 100/80watt H4 bulbs. I have a wiring harness kit for the H4 lights already but one of my relays is messed up. I need to replace the relays and want to know what Amp Relay I need to make the H4s work properly.

If you want, I have several HD70 amp SPST relay kits-I build mine as needed. If you want one, they are $59 each and I build them myself from Delphi spools...OEM rated stuff-not cheapo parts store wiring.

100 watts * 2 = 200 watts / 12 = 16.66 amps. A standard 30 amp relay will do the job.
