There are all sorts of sizes and colors of flourescent lights made to light up the interiors and exteriors of cars. Time, money, imagination and good taste are the only barriers to really lighting things up.

Me, I am waiting for electric paint. Why this hasn't happened is surprising. Imagine your whole car glowing, maybe with color changes, movement, etc. Not to mention the military applications. And make-up. Glowing nekked womens would be interesting.

Actually, it is hard to imagine BMW's thinking. They provide a light, but don't hook it up, have extra labor and two installation options on the line, have to design and specify two different handle bezels, list and stock two different parts (8 when you consider left and right, front and rear, with and without lights).

All this on a $50K (+) vehicle.

Car companies supposedly try to cut their manufacturing costs, but there are so many examples of doing things in strange ways that can only add to their costs.
