HI Guys so I bought some of the new look headlights on Ebay like these: https://www.ebay.com/itm/New-Ram-Sty...AAAOSwqCJcanRI


But not from these people.


They look great. and they work great. UNTILL you start the engine then the drivers side light starts doing all kinds of stuff, the turn signal stops and the DRL's come on and then the turn will blink for a few times then the DRL's flash.



They are fine when the engine is off.


I returned one already thinking it was the unit and they replaced it no quibble. but the new one does the same thing.



It has to be something to do with the RAM.


Any Ideas?

I would try some anti-flicker relays from diode dynamics before giving up, did your longhorn not have factory projector headlights?

Hi no its a Big Horn it has quad, I installed LED headlight bulbs with no issue into those.


Its just the turn signals in the new ones that are the problem.


I will check out the Relays, are they in the cab or in the fuse box?

They are inline with the headlight to provide an adequate wattage load back to the monitoring system. If you’re in the grey area the light will flicker or stay in a completely off state if the minimum is not met. The quads are a turn signal filament bulb and will draw more current than LED.

Tell us how you wired those in or how the headlight converts filament loads to run LED for the blinkers. From your initial post it may be a problem with the flasher or monitoring system. Do you get a Light out code upon start up from the heads up display, 5.0 or 8.4?

I can hear a Relay in and out of the cab, in the fusebox as well.


They are plug and play, just plug in, apapert from the DRL they have a seperate wire.


No Light out sign. its a 8.4


I tried a load resistor on teh turn signal but still doing the same when the engine is running.

I'd ask for a headlight wiring diagram and we can start diving in further.

One test for S&Gs is to measure the DC voltage into the headlight with the truck off(no alternator) vs on . Also, does pulling one or the other headlight plug off and starting the truck show any difference?

I had lights built from RetroShop and had the same issue you're having. I had a quad headlight and went to the factory projector style WITH ADDED switchback C-Bar halos and LED bottom. Even the harness supplied to me that is plug and pay for many guys, even the seller, didn't work for me at all. In the end and after endless tests I had to run my stock halogen bulbs in series with the turn signal wires. So under my hood, in a vented plastic box, my incandescent bulbs are on when the lights are on. I also did the whole job without cutting factory wires.
