my bad guys

i should have been more specific

i am wiring 4 PIAA 100W lights for the front of the roof rack

2 100W Harbor freight lights for the front bumper

2 55W Harbor freight lights for the rear of the roof rack

I have some 18 gauge wire, was told its not big enough

I am building a Fitch relay box, so i need wire from the box to the lights, and to ground

i know its a simple common sense question, some please chime in

Didn't the PIAA's come with wire?

I'd use that as a minimum.

Google wire size. http://www.powerstream.com/Wire_Size.htm Your lights are 100w, so that takes 100/12=8.33 AMPS (volts x amps = watts) (IIRC). So for steady power transmission, you need 12 gage wire. Hey, I am far from an electrical engineer. Some experts chime in and tell us the difference between chassis wiring and power transmission. I'd err on the conservative side myself.

This chart is better, because it takes wire length into accountm and you don't have to convert any numbers. http://www.rbeelectronics.com/wtable.htm
