    How do I track down a hyperflash issue. Lights were working fine until recently. No changes in over a year. They are aftermarket headlight and tails with the LED DTRL bar which were plug and play and have worked fine for several years. I get hyperflash intermittently now. I also noticed that when I have the light stalk in the parking light or headlights on position I get the hyperflash sometimes but never when all lights are off. Both sides get it intermittently. So I'm thinking it can't be one specific light since both sides started having the issue at the same time. Could it be a relay somewhere causing the issue? I don't even know if that makes sense.

    Yeah idk. Especially since it’s not all the time. Something is partially failing and getting worked down. If it’s happening now it will continue and possibly keep getting worse or indefinite. Sounds maybe like a connection issue / corrosion but not sure?

    truck looks good. I hope someone chimes in soon with some help and you get it fixed.

    I agree with corrosion or failing wiring. I'd say it's the internals of the aftermarket headlamps.

    No corrosion that I can see. Lights are only roughly 2 years old. Just don't understand why hyperflash when other lights are on but not when others are off.

    I have a multimeter but not sure how best to use it to diagnose. I'm guessing resistance is the issue but not sure where to test resistance. What kind of resistance reading should I be looking for. Can anyone help?

    Thanks but where is that plug located in the truck? Also, I should be measuring voltage at 1 and 6 and continuity at 9? What should the resistance be for blinkers to work properly?

    Right side of cab fuse box, you'll need to remove the Driver's side "under dash".

    Box on the left is the flasher relay where T11 is connected.

    Should be the relay in the taillights. My right side started a month ago. Now the left side is doing it periodically. Going to try resistors or go back to stock.
