driving lights wiring and switch strong enough

road hard · 02-10-2008, 10:04 PM

I have a 07 double cab 4x4trd and have installed a ARB front bumper. The bumper has no spot for the factory lights but would like to install 200watts of KC lights. Does any one know if the switch and the wiring from the factory lights be enough to cary the load or will there be a melt down of wiring?

I don't have a clue about an 07', but Before I had my 00', I started off with a '94 toyota pickup. I ran two baja racing lights on a roll bar, and two on my brush gaurd, and dad and I did the wiring. We ended up having to use 20 amp fuzes for each, because everything else blew. We did seperate wiring to aftermarket switches as well. I wouldn't imagine it a good idea to run two extras off your stock switch. But that's an older truck, and everything may be stronger now. Not for sure. I haven't really had a chance to tear into my new one.

200 watts=16.6 amps
and aftermarket switches are either 15 or 20 amps
so my guess would be to wire from scratch and have it get power from the battery (fused) as would be pushing the limits on the fuse block a bit

and the surge current of turning it on could go over 20 amps
and use a good gauge wire for it at least 16 but think 14 would be better in the long usage !
