I cleaned the dash yesterday and accidentally squirted some cleaner into the headlight switch. Following that the rhs side light front and back came on. Ok, I thought, a bit of fluid shorting the switch - take it out and wiggle it around a bit (so to speak

So I took the switch out and removed the wiring from the rear. But the same side lights remained on - how can that be? Surely all current goes through the switch so if i have disconnected it then no lights should work at all.
Unless I have discovered an intermittent parking light

Anyway - I put the switch back in and the lights went off! As long as it is fixed I suppose I dont care but it is puzzling.
