LED turn signals / markers work after rectifier, but not when Jeep is running

[Nate97tj]

Hi all, I have front tube fenders that use the factory side marker light as the blinker, I switched to 2 wire LED and after some research on here I got bridge rectifiers so they now work with headLights on or off

However…none of the blinkers work now if the engine is running AND the headlights are on, if headlights are off they work, and if engine is off the blinkers work whether headlights are on or not…so why would they not work with engine running and headlights on? Im stumped.

Sometimes there's voodoo in there with LEDs. When I did my nemesis highline fenders with their marker leds, I would get weird turn signal/marker light malfunctions like that too. Chasing demons, I wired in the oem bulbs in line with the LEDs and then everything worked fine (must be a resistance or ground thing that's above my pay grade). Since it worked, I just mounted the bulbs under the hood and the LEDs outside. Everythings worked perfect for years since. There's a better solution fix for sure, but it worked and I was tired. Now I'm just lazy and it still works. HTH. GL
