I have 4 6" 55W lights mounted on my roof bar at the moment. I would like to swap them out for 4 8" 130W lights. My question is could I use the existing harness and just connect the new lights to the old harness? The existing harness has a relay and a fuse per set of 2 lights.
I'm far from an expert on wiring, I actually hate it, so I was wondering if anybody could give me some insight.

Thanks in advance,
Josh

 

I would suspect not, If the lights are putting out double the watts the amps may be to high for the existing wires. When you get your new lights compare the gauge of wire in the two kits. If it's the same then I say just swap out the relay and fuses from the new kit and your good to go!

 

Right on, I'll have to see what gauge and fuse I have and compare it to the one I want
