Bought some after market head lights and the left side works perfect but the right side turn signal has issues. First one I had would work then not. Sent it back and now this one flick ere rs and then nothing. Any ideas?

Need more info. First off what did you buy? Second what kind of bulbs you running? Third are there any LEDs built in? Sounds to me like you just need to install resistors.

Projector headlights, led Day time running , led turn. I was thinking resistor also but why would one side work fine and the other not?

Oh yeah resistors will make it work. I’d put a resistor on both sides just to be safe in case something else decides to pop up on the drivers side later. When I got my recon tail lights my driver side kept giving me a bulb out warning and my passenger side worked fine put a resistor on both sides and no problems since.

Where do you put the resistor, which wire?

All resistors used on a vehicle for error canceling go between the two wire going to each bulb. Do not ground one side of the resistors to the body. For the dual bulb (turn/running lights) you have to use two resistors for each bulb. There are plug-n-play resistors for all bulb types, you just need to find a good mounting point that will tolerate the resistors getting warm/hot.

Crash seems to know more about the Alpharex lights than I do so I’d follow his word. The easiest way is to just get alphaobd and skip installing resistors.

I have a friend that can probably program LEDs in it for me. I was wondering about that.

With AlfaOBD you can also set any of the lights LED and/or HID and you shouldn't have to use resistors.
I have the Modifystreet/Alpharex headlights similar to the ones pictured above. I used AlfaOBD to set the turn and running lights to LED. I also bought the wiring pigtails from M² Mods for dedicated DRLs. I enabled them with AlfaOBD and have them set to drop out w/turn signal.IMG_20190713_153656215.jpg

Do you have a 2015 Ram by chance?

Yes it is a 2015 Outdoorsman EcoDiesel but the engine shouldn't make a difference(at least with nothing I've come across).
