Although these are marketed for model railways, they could be adapted for vehicle use. They can be painted over too.

Do you listen to music when modelling, or do you prefer silence?
I find having the radio on helps me concentrate. It's usually Planet Rock or one of the BBC speech stations. Although if there's a good game on then it could be football.
