Wiring Harness is 10′ long 18 gauge double stranded AWG copper wire. It has copper battery clips soldered to the black and red ends and flat spade fittings for two sets of lights on the other end as well as a 5 amp replaceable fuse connector assembly soldered at the battery end. With this you can operate up to two of my largest lights our Pro Series lights 2,800 lumens each or 5,600 lumens total safely from one battery connection. This is only a 4.8 amp maximum draw with both lights drawing full power or only 2.8 amps for two Sportsman Series. Order these when you place your light order and don’t forget the brackets !
