Resolved: 501 led lamps

[AUSTEN]

I have fitted the Bikevis 501 side lights onto my wife's car (I know it's not a bike but high visibility is not exclusive to bikes) and she is getting a strange problem when the lights are turned off the side lights flash? I thought that it may be some residual charge in the circuit somewhere, but fitting one led and one conventional lamp the problem remains. I need a tech's advice on this one. ???

Thats very very strange and not something I've heard of before...

There must be some kind of driver circuit for the sidelights, but I can't think of why there would be as a filament bulb requires nothing except a 12v electrical supply.

Probably Bulb Monitoring System, it will supply a small amount of power and check for load, enough to flash the LED, but not a filament bulb.

That makes sense, good call John  :D
