Car key light

First off, my understanding of electronics is very basic, I understand mechanical systems much better, but I am interested in learning more.

I would like to build a circuit which lights up a small light bulb near the ignition in my car after I close the car door and the courtesy light goes off so I can see where to put the key.

I am thinking that I could run a circuit parallel to the courtesy light circuit and put a capacitor on this circuit and a small light bulb. Am I on the right track?

Thanks
Matt
 

Re: Car key light

Read up on the 555 timer chip. This will give you the delay you need for a small LED to remain alight for say 30 seconds after you close the door. You will have to take a trigger from the courtisey light to activate the 555 timer
