How can I fix LED flickering

[rjohnson7581]

I have a 2021 RAM 1500 Classic 3.6L. I changed out the headlight assemblies to new ones that take H7 bulbs. I swapped the halogens for Fahren Termitor LEDs. I had a flicker which I didn't with the old assemblies I put LEDs in. Contacted Fahren and they said to try Nilight CANbus decoders. I installed them and the flicker is still there. What's the next thing I could try?

I read to try load resistors. Being new to the LED flicker, not sure if those are similar to the decoders. I read about them and it says they need to be mounted to metal but with the dust caps, I can't get wires through without drilling which I'd rather not do because of moisture in the headlights. When I originally installed the new assemblies, one of the dust caps was slightly loose and caused moisture to get in.

Attached are also the bulbs and decoders I bought.

Personally I wouldn't have bought Amazon special LED bulbs and canbus modules but thats another aside - if the output is good though and you are happy thats great.

You need to change the setting in the BCM under Body computer to "High Intensity Discharge Lights present" with AlfaOBD - this should turn off the PWM which is what causes the flicker

Thank you. I'll check this out later. The output is nice, just the annoying flicker. It only happens after I shift to drive. As I'm going down the road, they flicker for about 10 seconds then stop for maybe 30 seconds and repeat. Not bad to where they look like they're out but still very noticeable.

Keep us posted on if that works or makes any change
