Guys, need your help! I'm trying to wire 3 kc off-road lights to 1 relay/switch. Any help or assistance is appreciated.

Daisy chain the 3 light in with the other 2 and run everything just like your diagram . Make sure to use heavy wire between the lights , relay , battery , ground , I would use 10g but 12g wire might be ok

So, don't use the wire that came with one of the pair of lights?

Bad *** truck btw.

Honestly you probably could use it and it would be ok .. They just won't be as bright as they could be .. I'm assuming they came with 14gauge wire ? Kc is a good company so I can't imagine they came with junk wire . Some guys might say it could cause a fire if the wire is to thin . Make sure your grounds are connected to good clean non painted surfaces, most electrical problems trace back to a bad ground in my experience

Thanks for the help man. Well see how well this turns out. I'll post pics.

Below is a link to a voltage drop calculator. Power in typical lights are 50-75 Watts (High beam headlights are around 55 watts) this rating is based on a nominal voltage (Usually 12 although most automotive electrical is 13.5-14.5 VDC) to determine the Amp draw Divide the Watts by the volts (ex. 60 Watts Divided by 12 Volts = 5 Amps) if you have 3 lamps the total current draw when they are on would be 15 amps (note the Start current as they warm up {a second or two} is at least twice this) If the wire from the lamp to the Battery (and through the relay) is 6 feet total, at 12V DC the voltage drop on a 10 Gauge wire would be .18V or @ 1.5% the general rule of thumb is not to exceed a 5% drop. Fuse based on the Start current (30 Amps) or you'll be changing a lot of fuses. Sorry for all the numbers but there is a formula for almost everything. Enjoy the additional Light!
