light bar questions

[98tjsherry]

Alright so i got a 24" 120w led bar to put on my bumper. My questions are, what gauge of wire should i use, how big of an inline fuse should i run, and how big of a switch do i need. Im not the best at wiring so any help is appreciated. Thanks:beer:

Run the lights through a relay with the switch on as the trigger. Here is a wiring diagram. 120W should be a 12A fuse.

Will it hurt to run a 30A fuse

The fuse protects both your lights and other components like your battery. A 30A fuse could be used but for the cost of a fuse I'd put a 12 or 15A fuse in there.

This should give you overall idea on wiring an led light bar, see wire sizing table and wire grade standard.
