headlight relays

Thanks for all replies. I was going to just wire in to use the last few feet of factory wires on each headlight but I'll use my scavenged headlight plugs with fresh heavy guage wire. For now I'll use a 20A relay I have for the lows with a 30A for the highs, all circuits fused, with dedicated heavy gauge wire to battery ground, or equivalent. Test voltage drop after install. Oh, and SSD, where in Canada (or Calgary to be specific), can I get Nighthawks for my car????


TIA
