this helped a lot! thank you!

I bought a light bar online and its telling me my amperage and wattage. gives me wattage of 711 and amperage of 17.1...the math doesn't make sense.

any ideas there? what numbers should I trust? math is telling me that I need a 50 amp fuse for a 52" LED light bar...unlikely.

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?

Is the output voltage for each aux lifter 12 volts? So for example, on the 30 amp switch I can run a maximum of 12v*30a = 360Watts?
I am wiring a Christmas lights on my truck and want to use the uplifter switches. So my plan is for switch 2, wire in an inverter under the hood to convert my 12v aux switch output to 120v, then plug in there, from which I can draw a max of 360W. Sound legit?

I believe the electrical law is 80% of rated amps so 12 x 24 = 288watts by your math. You could power a relay though and the world is your oyster and run an inline fuse.
