Courtesy Light Timer and interior lights

I'll start off the car is a 1976 Duster but the entire car was rewired using an AAW kit. I have the dome light and the door switches wired up and working correctly.

I've been pondering the idea of adding in the courtesy lights. I have the ashtray light, column light, glove box light and also planning to add some LED footwell lighting.

I'm sure what all the courtesy light timer does or how it works. My car's electronics were destroyed when I got it and never got to see things in action. Is there a more modern way to have light timers?

I'm just tossing out idea's and hoping to hear yours as well.

Thanks,

Riddler
