Would it make sense to actually run a fuse for each relay so if the fuse blows I'd still have low or high beams left?

Body bolt, that is rather interesting, and rather conservative coonsidering they may use approximately 10 amps less than "30"(which is subjective).

Hey can anyone verify if the GMC trucks headlight harness actually has two Light Green wires coming from out of the firewall for the hi beams instead of one for Chevy harnesses?
I'm assuming this is for the extra bulbs and amperage draw?
