Does anyone know how i can run a flashing LED up to constant 12V power. I basically want it to turn on when i lock the doors and off when they're unlocked.

Have you got factory central, or aftermarket?

If you have factory central, open your front passenger side door, slide the rubber boot off where the door lock wires go thru the door jam, and locate the Yellow/Black wire. This gets negative 12V when the doors get centrally locked. Connect this wire to the negative side of a 12V LED, supply the Positive lead of the LED with constant 12V, and Bob's your uncle :)

Oh sweet man, exactly what i was after, so it will flash only when the central locking is activated?

According to my Haynes manual, it does :)

Can post schematic if you need it.

yep it's easy, i have done the same to my car and it works really well

especially at night, you can easily see if your cars locked from a distance
