This is my first circuit. In real life the spdt switches have three positions: on, off, and "door". There is for each lamp in the car. The single pole switches are simulating the door switch (i shouldve used momentary for accuracy but oh well) so, doors open; light comes on, door closes; light goes off. Real simple

Things i want to do but am not sure how.
  -make it only fade off when in "door" mode.      instead of when its manually turned on and off
  -make the delay before fading off longer 
  -having the option to adjust the duration of.  the fade or delay would be awesome

Im not sure if i did this in the most effective or efficient way i could, im just learning and still trying to understand exactly how all of the components function. And constructive criticism, advice, or help of any kind is welcome. Thanks in advance.

Here is a circuit that I have made for instant off and delayed off, see if you can adapt it for your needs. http://everycircuit.com/circuit/5077664239190016

That circuit would make it to where once you closed the door and the light had turned itself off. You couldnt use the light anymore without opening the door again. Its very similar to what i followed the first try.

Tried this. Didn't work. I have an LED "bulb" direct replacement in my car, maybe that's why? It has its own 161 resistor and a handfull of what i assume are transistors and a bridge rectifier...im not sure where to go from here. The light didnt fad at the functionality wasnt altered in the least.

Might have a zener circuit in it, works from 6 to 24v.
