Offroad lights wired to high beams
I was wondering if anyone knew if it was possible to wire off-road lights like a light bar for instance to your high beams so it will come one when the high beams are on and shut off when I shut the high beams off. Thanks

Sure is, I have a set of lights wired in exactly as you described. Pull your headlight, determine which wire is the 'hot' wire when the high beams are on and splice it. I ran the spliced wire into the cab, to a switch, then from the switch to a relay. The relay will have a wire pull directly from the battery to power your lights but the high beams will be the 'trigger'. That way, the high beams have to be on and the switch has to be on in order for the aftermarket lights to turn on. That allows me to pass inspection without any issues. If you need a wiring diagram, let me know, but you'll need a test light and, from there, it's no different from wiring any other aftermarket light.

Anything is possible with enough relays!!
Like Pugga said, it'd be best to run a switch as well.

I recommend using a switch & relay as well, I like having the switch as there are times that I can run my stock headlights but can't run my lightbar (for instance a light/medium snow will reflect too brightly off the falling snow with the lightbar but fine with high beams).

Only works when the switch is on AND the high beams are active. On the plus side, with the switch on and fog lights turned on, my low beam LED headlights are fine because of the additional current draw not making the computer think that the high beams should be active. No bambi mod required for my setup to work appropriately.

Here's a schematic using a relay.
Your high beam will be basically a "trigger wire" as the relay & the relay contacts will take the main power. The switch will allow you to have it on or off.
ALL my bright LEDs are wired this way and my switches are ALWAYS in the on position.... but my lights will not come on until I hit my high beams.
This is a schematic for OTRATTW/Carling SPST switch that is use in my KustomFX overhead switch panel:
