SOLID-orange

One of the members on Vehicross.info wanted a circuit that would light up the interior door handles of his car for a few seconds after he turned the key off to allow passengers to more easily find the door handles in the dark (they are actually difficult to find in the VX since they’re mounted quite low).

I came up with a circuit using a 555 timer in Monostable mode that looks for the ACC signal to dissappear, since it goes from 12V to float and since the 555 needs a pulse I used both a pull down resistor  to ground as well as an RC circuit to pull the 555 trigger back up.

I have a set of power folding mirrors for the 240, I’m thinking about customizing them so that they auto fold in and out with the ignition.

Here’s a circuit I drew up.
