Ern- I'd keep the single incandescent bulb (ever notice how it really shows marring when the vehicle is in the right postion?
) and get some additional lights.
If you want to avoid getting into stuff that'll require an electrician, I'd just get some more halogen lights on tripods. You can add an incandescent trouble light for
final inspections if you find you need it (mainly required with paints like silver) and/or a movable fluorescent light for general illumination that doesn't get hot.
If you want to pay an electrician the sky's the limit
