Another electrical gremlin

[Buffoon]

Noticed the other night that when switch the engine off one of the lights at the front sometimes flashes on briefly. Don't know if it is side lamp, headlamp, or what it is.

I always switch off heaters, lights, etc with engine still ticking over, then switch off and as stated there is a brief flash of lights. Nothing lighting internally, just front end.

Has anyone else experienced this gremlin?

Suspecting it is a current reversal owing to a degrading regulator block, but as I have only spent 5 seconds applying my mind to it this could be total tosh. Question is, where is the circuit being made? With light switch off, how can this happen?

No idea why - It's because it's a Cerbera On mine only one sidelight comes on when the ignition is off, switch the ignition on, and they both come on, I live with it, I'd probab;ly go mad if I tried to trace the problem and figure it out.

Simular thing happened to me once when I parked out side my mother's place, switched car off and both headlights were on and couldn't switch them off. When I came out after 15 mins lights were off. Never happened again so put it down to it being a cerb.

My headlights flash sometimes after switch-off, but they're HIDs so probably just the converters discharging (or so I assume).

Mine does this too occasionally.

I rewired the front lights on mine with new bulbs, relays etc to improve the lighting, anyway, as coincidence would have it, the week after i finished the job the lights started coming on their own...turned out the switch had gone US, bad luck or switch 'over use' - god knows!!

If it drives you mad - maybe try the switch.
