Hi gang,
I pulled from the bottom of my roll away a pair of nos but non descript fog lights. They are 100w H2 units that pull about 8.5 amps and pre wired with 16 gauge wire pigtails. My question; Wiring this pair of light to one switch. Is 14 gauge wire satisfactory? I've got a load of 14 gauge but minimal everthing else, and I think it'll be fine for up to a 14 foot run, unless the data so far is inaccurate. So far research on the web yields tmi about non related elcetrical.

Thanks and a lift of the lynch lid for any responses.

if its only 8.5 amps the 16 Ga is fine, but to be safe for the switch i would wire it to run off of a relay

I went with the 14 ga I had and with the relays for each set shortening the length it's working fine so far. Thanks!
