Hey Everyone,
I have LED turn signals in the front and back. I've installed the LED flasher module.

With the engine off, and the vehicle in the "ON" position, signals work as they should. Nice consistent blinking, both left & right.

Once I fire the engine up, the signals tweak out and flicker left & right.

The only thing I can think of is when the engine is running, the alternator is putting out above 12V and that is causing it?

Suggestions?

Thanks a ton!

I would think it would be the other way around, IE lower voltage would give trouble. Have you actually measured battery voltage?

Here's what I think of LEDs.

They have not been generally properly researched, IE for compatibility, for proper beam pattern and so on

Many are cheapo Chineseo imports that have no interconnection to things such as NHSTA or DOT and IF THEY FAIL and get you into a crash, you might find yourself in a sticky situation.

Typically the voltage range an led will operate properly in is nothing less than amazing. I would bet on electrical noise from the ignition or alternator messing with the blinker module. A mechanical voltage reg could be confusing things, or is it solid state? Also, gotta make sure your ground paths are good and tight. I love this stuff, wish I were there to help in person.

Phil, I have the exact same issue with my digi-tails. Did you find a way to solve it?
