I'm about to finish up the install of my aux switches, and one of the things I plan to add is some street legal aux driving lights. I'd like to use one of the aux switches to control them, but not just simple on/off. What I want is to have them powered on when I turn the switch on the first time, then if I turn them off and on again I want them powered if the high beams are on, cycling back and forth between "on" and "on with high beams" each time I turn the switch off and back on.

I don't want to just have it always powered buy the high beams, or on if the switch is on because I also want a full off condition, regardless of what the high beams are doing. I could accomplish this using two aux switches, but that just seems like a huge waste.

I can get the high-beam trigger from my VSIM, so that's a simple input.

Any thoughts?

When I did it on my 97 GMC I used a on/on switch. In one position it would come on with my high beams and was controlled by the stock high beam switch. The other one turned them on by themselves.

Yeah, that would be pretty easy to do with the factory aux switches and an additional SPDT relay, but I’d really like to have a completely off option.
 
Use the highbeam trigger from the Vsim with an aux switch as an interuting power to #85/86 (which ever you are using for the relay coil+),so the high beam will work with the HB stick but you can can turn the aux switch off to turn the lights off. I have used this on many trucks over the years

Yeah, but then how do I turn them on without the high beams?

Looking for 3 states:

  1. On
  2. On with high beams
  3. Off
 
You need a latching relay.

That and a AUX switch set to momentary and your VSIM line should get you there.
 
my truck didn’t have the factory vsim. I tapped into the fuse spot labeled vsim with a fuse tap. Hooked my aux controller to that to control my aux lights front/rear and bed. It only works if the truck is set to on or running.
