[QUOTE="B E N, post: 1440126, member: 33355"] Assume the worst case that the battery will be partly drained when you hit the light bar, and the engine is off: 711 watts / 11.5v =61.8 amps. I like a little overhead on my relays, Viair 93980 is rated to 80amps and pretty budget friendly, fuse the line to 75 amps and your good to go. 711 watts seems like a lot for a light bar... Is it incandescent? [/QUOTE]
