My car has instrument dimmer lighting and I do use it frequently on unlit roads. I didn't engineer it that way, the headlight switch just did it. I never gave it much thought til now though. My interior is illuminated by Lunarvision upon opening a door. Never gave courtesy lamps much thought til now either, though I wouldn't bother. Maybe if my car had a top I would reconsider. But then if my car had a top I would reconsider owning it.
