How do I make my dome light fade away when you shut the door?

Thats what I love about this site, no matter what is said, someone disagrees.

Capacitors are what is used to make those dimming "auto" features work, sometimes, as far as the specifics of setting it up or engineering it properly, I don't care enough about it to invest the time. I was just giving the guy a place to start.

BTW I seriously doubt you know what "big" means relative to size of the bulb in the dome and associated wiring.

I seriously think I DO

I was first licensed as a radio amateur before I was out of high school in 1966. I spend 6 years in the U.S. navy maintaining TACAN and ground controlled approach RADAR (GCA, or Precision Approach RADAR--PAR)

Caps and timing circuits are "what make RADAR work." I used to have a very good understanding of RC time constants

In my later years, I've repaired and modified a considerable number of amateur radio "linear" power amplifiers, all using very high voltage power supplies, and all using some fairly large filter caps in the power supply. We're talking anywhere from 2000-8000 volts DC across, say, 20-40 mics of capacitance. In other words, it can kill yer ***.

My point was..................and I still stick by it, ..............that if you just strap a huge cap across the dome light switch, it will probably "fix the switch" in short order.
