LED indicators fast flashing

torq2u · Jun 28, 2023

I recently replaced my old bulbs, rear indicators, with these

WY21W Amber (585) 7440 (12V-24V) 7* 3030 SMD Canbus LED Bulbs 3000K Car Indicator, Turn Signal Lights, Pack of 2

The hazards still flash at the normal speed, but L / R indicators flash at double the speed of the old bulbs. Is this ok? Assuming they are less than 120 per minute for MOT purposes.

Thanks

Just put the old lamps back in the indicators.
the fast flash is because the turn signal relay is sensing a reduced current and assumes this is due to a failed lamp.

Thanks James. I think I’ll do just that.
