Been spending a good amount of time studying the lighting schematics for my truck; little bit of progress on ideas for the electronics, but I need more information on how the DRL PWM operates in terms of pulse frequency to help with electronics design; looks like I will need to get an engineer buddy to help get the measurements from the DRL and LED operation. Not sure when that will happen given holidays and work schedule...Will post back results when I get them.
not sure how it works
gm used like a bunch of ways to implement it
only way to know is with a Oscilloscope there is some super super cheap ones out there
you can try a loaded circuit with the LEDS (use a diode then smoothing cap rated at lest 24 volts to handle any spikes) see how that works use some cheap Chinese LEDs to do it
other wise it's going to flicker really bad there is some reports it's a 50Hz signal
