i would like to put a LED in my dash that flashes whenever my ignition is off. i have easy access to power, ground and ignition (i.e. it's +12 when the key is turned). i also have a few red LEDs.
now, does anyone know how this could be done? would i need to get one of those LEDs that flashes on it's own, or is a normal one cool? i assume i will need some relays and diodes (i have some diodes).
BTW the car is driven every day, so i assume a LED wouldn't drain my batt (and i will hide a switch under the dash so i can disable the LED when i park in my garage).
You wouldn't need relays, just a switch and a timer... Depending on the speed of the blink (which is set with the various stuff connected to the timer).. I believe L555 timers are the accepted generic item, but I'm not quite knowledgable enough to give you any more info than that... Anybody else?

Buy a 12 volt flashing LED at Radio Shack. Hook up + wire to constant and - wire to ignition. Wallah, turn the car off and LED blinks.
