We got started a tonight, sort of, by decorating the car with Christmas tree lights for our night out at the drive-in theater. (They showed Superfly!) It was a quick-n-dirty installation: I used electrical tape to attach the lights to the exterior, and my friend Lisa explained about DC inverters that convert the cigarette lighter into an outlet.
We turned on the lights when the sun went down, and they looked pretty good in the dark! It's hard to tell in the picture because the flash went off, and made the car look too bright. I heard someone in a nearby car say, "how come our car doesn't do anything like that??"
However, we were not the most impressive car at the drive-in, not by half. One gentleman brought an amazing Cadillac Eldorado, tricked out with running boards (carpeted!), giant round covers over the headlights, and these tire-shaped decorations on the sides. It was similar to the car in Superfly, only it was a convertible so it was even cooler. The owner told me that he'd had it for 21 years. It was truly an awe-inspiring sight.
