LED Turn Signals

Having a problem from keeping the led signals from surging when the vehicle is on, when the vehicle is off they are fine until it is turned on and they kinda have a blink to them (Surge). I have installed the resistors and still no luck! Anybody had this problem?

Have not heard of this yet. I used FORScan to get rid of the hyper flash after switching to LED but have not heard anyone complain about the situation you describe.

Do you by any chance have a topper on your truck? If so it could be wired in the incorrect way.

I had an issue with opposite rear led lights blinking very faintly after cap install. Took it back and they used a different connector to fix problems.

Is it just your LED turn signals? If the are cheap lights, they may have a chip problem.

I would put the stock bulbs back in, verify there is no issue, then try another LED manufactures lights.

The other possibility is you have a load on the turn signal circuit that’s causing it. But you should see it with the OEM lights also.
