    Light that turns on when unlocking vehicle

    Hello everyone!

    So, I have a 2012 WRX sedan.

    I'm going to install some LED on the exterior of the car.

    What I'm wondering is that if there is anyway I can wire the LEDs so that when I unlock the car they already turn on. Just like the interior lights. When you unlock the car they tun on.

    The problem when wiring them with the interior lights is that after turning the car on the LEDs turn off unless you keep the interior lights on, what is something I really don't want to do.

    Does anybody know a way around this? How can I wire the LEDs?

    Thanks a lot everybody for the help

    I think that there is a way: If you connect a simple circuit (as in this link:

    Basic Electronics Tutorial 10 - Transistors Part 1 - PNP and NPN on Vimeo

    ) to the door unlocking circuit, you should be able to charge an electrolytic capacitor with the unlock circuit connection. This charged capacitor will close a circuit (by applying a gate voltage on a transistor) that turns on a light, keeping the light on for an amount of time dependent upon the gate-leakage current of the transistor and the capacitance of the capacitor.
