I'm thinking about just using my iPod and headphones whie driving. I once saw a guy doing that in an old beaten up car and thought "man that's ghetto" but now I'm kind of liking the idea
I really like the idea. It is SO much lighter than soundproofing the whole car. I use hardware-store hearing protectors with a useless anti-noise circuit, but the mp3 jack works just fine. And they are Really easy to keep away from thieves.
Using a resistor to dim incandescent bulbs does reduce power use overall, but not in proportion to the reduction in light. With the filaments down to bright orange, power usage might be down 50%. An ammeter patched into the relevant fuse slot would provide exact information on usage - you could pull any other bulbs on the switch to isolate the dash draw.
