Fix for hyper flashing turn signal after replacing headlight

I replaced my headlights assembly with led assembly now I have hyper flashing in turn signal. Does anyone know of a led compatible relay to replace the one that came on the truck.

 

Usually there is a resistor added to the circuit to prevent hyper flashing.

 

I did see a resistor on the harness. But I still have the issue. I traced the clicking back to a relay under the dash left of the e brake

 

Could be a bad resistor. I recently had that with one of my aftermarket tail lights. Replaced the resistor and working fine.

 

Thanks will check into that

 

I looked for a pop-in relay board replacement for my 2008 when I went to LED turn signals. I did not find one. Big ol' resistors in parallel with your LED bulbs should work, but replacing/changing the flash module is much cleaner. I took the turn signal board (yes, near the e-brake) and changed the current sense resistors (RS1 and RS2 designators on the PCB) to a higher value. I started off with about .12 Ohms since I had resistors I could parallel to get that (shown in picture), but occasionally I would get the hyper blink still so I changed to 0.15 Ohms and that was good (someone on a forum had suggested 0.15 Ohms and they nailed it).

 

What set of headlights did you install?

Think I found the problem. One row of my turn signal are not working.

 

Make sure all of the connections inside the headlight housing are tight. I installed a new set and got a hyperflash. Turns out one of my bulbs was simply disconnected and that will cause it. You'll have to look deep in the housing to be sure.

 

This was helpful for me, thank you. I had the same issue on my 2008. I followed this walkthrough and installed a couple of 0.15 Ohm resistors and that worked like a charm!https://www.youtube.com/watch?v=ORqtLwXfy-4
