Adding 3rd driving light question

Adding 3rd driving light between the two existing. Can i tap it into one of the existing lights wires without causing problems? KC 130w.

 

130W lights draw around 11 amps each. The wiring kit you have likely has a 30Amp relay and wiring to support 25 Amps. You'd likely blow the fuse. Upsizing the fuse is dangerous since it's there to protect the wiring and it's sized for that size wire.

I would leave what you have in place. Add a second fuse and relay coming directly off the battery and use that to provide power to the new light. You can tap the existing light circuit to trigger the new relay and have all your lights on the same switch that way.

 

Thanks for the detail. I appreciate it
