Front LED not flashing ??? ITS WORKING NOW ,THANKS.

[goff]

Are there any Auto Electricians , OK my car as LED rear light cluster + LED flasher unit 30w , so thought i would fit LED bulbs to the front indicators ,the nearside works OK , but the offside is acting strange - Fitted LED bulb it would not light/ flash , put the 21w ordinary bulb back in , flashes ok , so i tried the LED bulb on a battery and it works ok , next i removed the front flasher unit by disconecting the bullit conectors under the wing ,so i put two wires in the harness and and on to the bulb and the LED bulb lights up , so i tried the front flasher unit with LED bulb in on the battery and it works ok , swapped the female bullit connectors still works , connected it back up , IT DOES NOT WORK , I am baffled ??????. Any help would be appreciated ,
No i have not wired it wrong way round , works with 21w ordinary bulb ok.

Sounds like the flasher unit needs more load - which if it is a proper LED one it shouldn't.

If you fit all the LED lamps and then add in an the incandescent one as an extra does it all work?

Does the indicator unit earth through the body of the lamp housing or via a wire into the wiring harness? My suspicion is an earthing problem which doesn't show up on the incandescent bulb due to the higher current flowing compared to the LED,

I had a similar problem and it was a poor earth, good enough to make a ordinary bulb ok but bad enough to not allow a LED to work . Roy

Goff, some LED Lamps have a Polarity on them. If it's possible, try reversing the connections to the LED itself.

If you can't, try swapping the 2 LEDs on the front with each other and see how they respond.
