<<Just curious, why do you need two 30-amp relays to switch power to two
55 watt bulbs? Wouldn't one carry enough current for both lights? I
think they are fused at 10-amps each, the most current that relay would
ever see is 20-amps with the stock bulbs.>>

I think this set up gives you the option to go to higher wattage
headlamps ( 80/100 ) without suffering any switch failure consequences.

The fuse's can be changed to 20 amps each to handle the bigger lighting
load pretty easy.
