CECAA850 Posted April 30, 2012 Author Share Posted April 30, 2012 Doc, as far as I know, the lights are all DC. I don't know what the duty cycle is but I'd bet it would be 50% on, 50% off. Quote Link to comment Share on other sites More sharing options...
JJkizak Posted April 30, 2012 Share Posted April 30, 2012 I believe he only wants the lights to come on when he turns the switch on, not when the ignition is on. JJK Quote Link to comment Share on other sites More sharing options...
superedge88 Posted April 30, 2012 Share Posted April 30, 2012 A 30 amp relay with the existing wire with DC and signal voltage as the trigger and the relay feeding battery voltage to the bulb. Quote Link to comment Share on other sites More sharing options...

That wont work. When the signal wire goes into it's PWM state, the relay buzzes like a hive of bees from the on off pulses. Quote Link to comment Share on other sites More sharing options...

JJK No. My end goal is to disable the daytime running lights. The low beams have power and ground supplied when low beams are called for. Those are the only 2 wires running to the bulb. When the low beams aren't called for, the low beam bulb is used as a daytime running lamp at an output that is less than low beams. Instead of a constant 12 volts, it gets a pulsed voltage to reduce the output. Older styles got a reduced voltage. Newer styles (like this) keep a constant voltage that is pulsed.

superedge88 Posted May 1, 2012 Share Posted May 1, 2012 Then easiest option is simply rewiring using a switch and relays and bypassing the pwm, not knowing exactly the reason and exact goal makes things difficult. Quote Link to comment Share on other sites More sharing options...
