Max AMP on headlight high beam circuit?

[KipperKahn]

New owner of a 2018 Super Tenere ES.

I picked up a couple 60W LED light bars with the thought of splicing them directly into the high beam circuit.
Combined, the High Beam and LED Light bars would be 20A i believe.

Can anyone tell me what the max amp that can be put through that circuit?

Use a relay.

The headlights on the bike don't use a separate filament for the high/low beams. Switching to high retracts a shutter, so the current draw is always the same. That being said, there are plenty of threads here about adding aux lights, and I can't stress enough what bigbob said: use a relay. The factory wiring and fuses are sized for the load, with a little bit of headroom. You do not want to loose all of your lights by overloading that circuit. Also, make sure to use a fuse close to the power source. At 60W, your LED bar pulls about 5amps at 12 volts, which is probably a steady state output, there may be a current spike when turning the lights on.

I have a LED Wiring harness with a switch/relay/fuse. Plan was to wire that to the high-beam wire for power and run the ground to the Battery.

OK, so before i go blow something up, anyone want to check that i have my wiring correct for my project.
I have a the relay, fuse and a 5-Pin Rocker switch so i can turn off the LED lights if needed but still use my high beam lights.

Not quite sure why you are using a 5 pin rocker switch. All you need to do is interrupt the pink trigger wire from the high beam to the relay to shut the LED light bar off. You only need a simple, low voltage 2 pin rocker or toggle switch for that. I did it that way on my LED spots wired to come on the the high beams. I think what you have will work, it's just over complicated. You don't need to cut the ground to the relay, just block the pink trigger wire to the relay to shut down the LED light bar. No 12v to the relay trigger side, no switch to power the high draw 12v side to the light.

The 5-pin came with the wiring harness, thats the reason i planned on using it. The bottom right pin is the built in Blue-LED in the switch.

Well, no reason it won't work as you have diagramed it. You have all the right elements in place. I found that it was very rare that I could use high beams in circumstances where I didn't want the extra LED light too. Wire it up and show it off to us.

Finally got my USB / Volt / LED Switch Panel finished. I used 1/8" Kydex T Sheet for the backing that the plugs and switch are inset.
