    So I currently have the caliraised LED bar installed with a switch by my leg. I was wondering if someone (substantially smarter than me) knows how to wire (and can explain it) so that when I press the button by my leg it enables the bar, but the light bar won't turn on unless I toggle on my full beams, and if I toggle them off the light bar goes off also. And obviously when the button is not pressed toggling full beams only does the full beams? Is this possible/doable?

    Thanks

    If I think I'm understanding you right you would have to wire your light bar like this. Find the positive wire that activates your high beam lights. Tap into your high beam light positive wire and then run the wire to your switch, Then from your switch you will run to the light bar. You might be able to tap into your high beam switch and run off of that to your secondary switch and then to your light bar. Depends on how thick the wires are cause you dont want to smoke a small wire. This is not a project that I would want someone walking me through on a thread. Maybe see if there is something to the Tube where someone has done something similar?

    There’s no way I’d run what is likely a ~15-20amp LED bar through whatever cheapo low amp rated switch they threw in with the light bar. That’s asking for a wire meltdown.

    You need to run this through a set of relays. Just off the bat I know you could do all this with a proper relay setup but it’ll be a little more complicated than the likely SPST relay that came with the LED bar.

    Maybe someone else will help out. I would but I don’t have time at the moment.

    Just don’t use your high beam circuit as the power source. That’s a no go. Use it as a relay trigger only.

    Did this yrs ago but the paperwork is buried.

    Run a relay and a switch.

    You're not going to want to wire the light bar itself in parallel with your headlight. You'll blow fuses and it's bad for the wires. If you just want the LEDs to turn on with the high beams, find the high beam positive wire that goes into the bulb, splice into it, run a wire from that splice to the 86 pole of your relay (if you want you can put another switch in series with that wire on the 86 pole so that the LEDs will come on only if the high beams are on and the switch is on at the same time). Run an appropriate gauge wire and an inline fuse from the 30 pole to the positive terminal of your battery, and run the 86 to your positive on the light bar. Ground the negative wire for the light bar and ground a wire from the 85 pole.

    Sven...get out your volt meter and find the hot for high beam near either head light. (Remove bulb and test the terminals in socket with high beam switch on). Get a wire tap and run it to a standard auto relay, it will draw about 1/3rd amp. 86 in diagram above. Make sure the relay’s switch terminals 30/87 above, are rated to drive your lights. Put the relay switch terminals in series with your dash switch. Then when both are on the bar will light along with your high beams, else just the high beams.

    Must use a relay. KC diagram pretty similar:
