Pulsing Front Turn Signals

rennwerkes · 12-11-2020, 01:09 AM

Getting a weird pulsing from my front parking/turn signal bulbs. These are the amber bulbs in the front headlights.
Changed them out to LEDs and coded everything to off. But the bulbs started to pulse. They don't flicker on and off like a rapid turn signal but does a constant quick pulsing. Any ideas? Did I miss anything in my coding?
Thanks!

Thought there'd be some ideas but regardless, I think I figured it out.
The bulbs I was using were overheating causing the pulsing.
Changed out the bulbs for slightly lower wattage leds (and different brand) and all seems good at this point.

Thanks for the update. Probably no one had performed this modification using the same brand of leds, hence the lack of response. Hope it works out!

I'm glad I hopefully found a solution to using LED's for the turn signal. So much brighter than regular bulbs and instant on and off.
