so i'm admiring my friend's car dome light the other day because it fades off when he closes his door. it was a computer-controlled fade, but i got to thinking, why couldn't a capacitor do the trick? so i tried it out, but quickly realized i need a much bigger capacitor than is practical. so anyone have any tips? is there a way i could do this with relays/capacitors/resistors? or should i stick to icu's controlling it? i also thought i could replace the 8W dome light in my car with an LED and just using a capacitor, but that is less desirable as it's much dimmer. i would appreciate any thoughts/tips anyone has.

Try this one. I don't know how good it is, but it's worth a shot. What I want to try is a dimmer module from another car- the one from a Saab 900 or 9000 looks like a good bet. I don't know though if it fades the lamps out, or just shuts them off after a few seconds.

thanks, at least that one gets me started...i appreciate it! (i probably will end up trying to just use another car's, seems easier anyway).
