This is more of a brainstorming thread then anything as of yet
Why yes PWM headlight control, Found on a few newer cars, specially Canadians with the Daytime Running Lights engaged. I do believe the PWM is to prevent people from dropping in those cheap Plug and Play HID kits into cars with Halogen Projectors, so the car will play havoc on the "HID" system even with relays (I've heard people complain about "buzzing" relays).
NOW if one can measure the PWM of the power (or ground?) to the headlights to determine what frequency(?) the headlights are at for the DRL and for "full" power can one build a circuit that can translate that into a simple on / off output? with a Theoretical figures of the DRL frequency is 50% and "Full" is greater then 90%. So when signal is around the 50% rate the circuit can control a relay A (Too another DRL module or some other DRL setup) and when that same signal goes up to 90+% it'll control Relay B (To Give full battery voltage to the headlights)
Even thou most modern cars also control the alternator so you can be driving around with 12.4 volts at best instead of 13.4-14.4 **broken link removed**, but having the headlights going through a PWM setup isn't helping! Which is why i believe the headlights are dimmer on my '13 fusion then on the trade in '96 XR7, which had 13.3+ voltages constantly and no PWM nanny stuff
Thank You
