Wire Gauge Question

[moribundman]

I have one relay (30A) for a pair of low beam headlights (55W each). The relay has two terminals 87. A 12 gauge wire will run from each terminal 87 (positive "out") to each low beam bulb. What wire gauge is required from the power source (battery/alternator) to relay terminal 30 (positive "in")? Will 12 gauge be sufficient or do I have to go to a larger gauge?

The chart in that thread does answer my question. Thanks for the link!

No worries. I haven't been able to get away from that website lately. Lots of good information. I will be doing the same thing as you soon, as soon as my X-treme power bulbs get here.
