I don't understand. This is the largest harness I can find. It's only good up to 300w. What does everyone else do with light bars larger.

That sticker could be misleading, 480 watts output is not the same as 480 watts consumption. Just looking at the wired pigtail on that light no way would I try to push over 40 amps through it.

Now if it was 10 or 8 gauge wire maybe, but it looks like typical 14 gauge wire on my 50" light, it is 400 watt draw of 34 amps ran by a 40 amp relay and fuse.

If you don't understand any of the better get hand's on help, once the pretty blue smoke rolls it's too late.

Thanks for the reply. that's what I was thinking also. the wire is 14 or 12. I will check that out to be sure. if its only 14 I don't see why I can't use a 300w set up. I may just build my own & do it a little heavy to be safe.

The longer the wire the larger it needs to be.
They may be "getting away" with a smaller wire for that 12" length. But if you try a 14ga between the roof and the rest of the circuit you may be at 20+ feet of wire.

I'll check to see what gage wire mine is.. but that's exactly what I would do. I just don't understand the wattage rating. You could hook the pigtails up to a spare battery and test the amperage with an amp clamp. I did that on mine to be sure the 300 watt was correct.

This is the sticker on the light. It says 480v + or - 25w. Does that mean I would need a 45 amp fuse.

The wires don't seam to be that big. View attachment 35006

Have you thought about running the switch sized usb charger with a voltmeter built into it? I dont have a pic but others have posted pics on here of them.

One thing that I have come to dislike about those is that you cannot view battery voltage when you have an accessory charging from one of the two ports.

Really? It worked for me the other night just fine.

I've got two, one for each battery. I'll have to try them both.

I have one and I have a battery switch so I can alternate between the 2 batteries or turn if off. It works for me when it is charging something.
