I would like to know if it is possible to take a circuit that is sometimes PWM (for daytime running lights (DRL) on low beam) or Constant 12V (regular low beam) and use that state to activate a switch (or relay)? Is this even feasible / possible?
What I am trying to do is take my DRL and relocate them to the front parking lights, saving wear on the low beam headlights, but still have normal low beam headlight operation. I understand only the basics: such as solid state relay operation, choosing proper wire sizes, and I have even used a blocking diode, but that's about it.
I hope this hasn't been covered, but i can't find it in a search.
