negative, i dont care if they are direct wired with 1-00, the switch is the weak link, you can buy switches that will handle it but they aren't cheap compared to a relay. I HAVE had a switch burn up just above my right knee, it was decent sized wire, the switch burned up, grounded the hot wire on the dash/column, super heated enough to melt the insulation all the way back to battery...well guess what, it also ran through the firewall with the main harness, so it fried a bunch of those wires as well. took me an entire weekend to cut and splice wire back in. It was an 89 dakota and it never fully functioned properly again for a 2$ relay...no thanks, ill pass

The shorter the run of cable between the battery and the light the less voltage drop and the more light you'll get out of the lights. A relay off the battery at the light is the shortest path. Then it can be triggered by a simple switch. I run my radios the same way. They sit on a relay with high current handling and are triggered by either the auto switched outlet or a bypass switch.

Look at the write up for the kolak wiring harness for the stock lights, it's a major design flaw in these things. http://www.jeepforum.com/forum/f13/c...pgrade-660428/

yes, there is next to nothing for current there, the lights are grounded right?

edit, yes you're good

A 35w fog light isnt likely to burn up a switch unless its an uber cheapo china brand rocker switch which I wouldnt use even with a relay. I get what your saying and am in total agreement about using a relay but for small stuff as long as its fused lower than the amperage of the wire and switch itself there wont be a problem as the fuse will pop before the switch.
