LED Light Bar Comes On With High Beams

Can you wire an LED light bar to come on with your high beams?

Then have the light bar turn off when switching back to low beams?

You could always add a relay to power your light bar and have it triggered by your high beams

You can wire it that way, but it'd be illegal for on-road use.  Most all state laws prohibit more than 4 driving lights being on when the high beams are activated.  That's why the fog lights turn off when you hit the brights.  If you only use high beams on a trail, or there aren't any Rosco P. Coltranes in your area, go for it.

I know this is an old thread, but a simple toggle switch inline to the relay will disable it from running with your high beams when needed.

Yes you can have whatever you want come on with the high beams.  On my '09 when I turn the high beams on my lows stay on and the 3 little cheap light bars I have behind the grill also come on.  Eventually I'll make it so the "fogs" stay on too.  I can't give specifics b/c I'm clueless, I just know it involves relays.  Just like my auxiliary lights in the rear come on when I up the truck in reverse.
