so i hooked up in my buddies truck, a 2012 dodge ram 1500,led turn signals, low and hi hid conversion kits. now i have a fuse, relay with the hi black and red stock wiring for the highs going back to the relay and from there the ballast connections for those are shared by a split connection with one warning canceller. they are 55w ballasts and the hi beams work fine. the lows however are where i have my problems. they are a 35w ballast but there is no relay put for those. i have the power directly hooked to them through the stock wiring harness for each individual low. from there they each have a warning canceller then go into the 35w ballast and then to the light. the lights will turn on and stay for a few minutes but then you start the truck and turn the light switch from auto to on and they stay turned off. i tried wiring a 60w resistor with just the driver low connected just before the canceller and the problem persists. the light will sometimes be on and then turn off. the ballast seems to be cycling and i cannot figure out how to correct it. can anybody help?

 

also its a 4 lamp set up

 

you need a HID anti-flicker capacitor. when the car is off the lights get plenty of power but when the engine is running the ballasts don't get enough power. this should fix your problem.. I had the same issue with my fog lights on my 2013 ram 1500.

 

i thought the warning cancellors are supposed to do that. they are a capacitor after all.

 

I think the warning canceller is a resistor, not a capacitor. A resistor adds artificial load so the truck's electrical system thinks a standard bulb (i.e. standard current draw) is present. A capacitor provides an 'energy reserve' that evens out the flow of power through a system.

On my 09 I only needed them on my low beams. Fogs work fine without it. Simple plug and play with my kit and no extra wiring or grounds. Maybe there was a change in the later models.

 

I needed it for both my low beams and my fog lights. maybe one day they will have an all in one ballast that has all this so theirs less things to mount.
