they work in the same manner as the main interior light does, so if i were to walk out to car in the morning and unlock the car, they light up, i then get in the car (as you do) start the engine and then the lights go out. Park up, switch off, open door, lights come on, get out, then lock doors and lights go out. So they do whatver the main interior bulb does apart from when you switch it on manualy.

I have 3 circuits each having 4 green LEDs (6 down each pillar) They work at there brightest with 4 LEDs as they are 3volt bulbs, i tried it with a circuit of 5 bulbs and there were a bit dim, 3 bulbs is also bright but any less then they blow. Bought a pack of 50 from ebay for £2.99 which you cant beat and they are brilliant LEDs.
