Picking up a surco that comes with 2 KC daylighters. It does not come with the wiring harness. Do I need to get a relay and what guage wire should I use? I have no idea if they are 100 or 130 watt. Any help would be great.

 

I'm not 100% sure but i run 12 gauge and a relay. Relays are nice unless you like electrical fires haha. I have two Hellas as my driving lights and 4 overhead "bajas" that the only thing the same is the housing. Both I run 12 gauge and a relay. Anyone else have ideas? I don't think KC's would be much different.

 

I put a set of 130 watt daylighters on my Nissan, when i bought em they were new but the guy used the wiring harness out of it. I went to the local O'Reillys and bought a offroad light kit they have, comes with a toggle switch, all the wiring and also a relay, cant remember if its a 30 or 40 watt relay. Also comes with a fusable link. The kit is like 13 bucks. Its worked great for me with no problems and been running it for about 2 years now.

 

So you could use a less wattage relay then the lights?

 

 

Thanks frank that helps so you guys think im okay buying one of those 55W wiring harnesses and useing that?

 

Bump anyone?

 

Nope, you'll melt it.

 

The relays and fuses are rated in Amps not watts. The lights are rated in watts. 12 Ga. wire, a 20 Amp relay and fuse would handle those lights even if they are 130 watt.

 

each 100 watt light will draw roughly 8 amps, so i wouldnt go past 2 lamps per 1 12 gauge wire. i would personally do 10 gauge, but thats cause i like to over do things haha

 

If youve got an O'reillys store in your town go there and get the kit im talking about. Its made by Optronics and is a 40 amp kit.
