Abstract

A lighting system for a vehicle having luminescent or “glow-in-the-dark” markings placed on an interior surface of the vehicle and a light source located remotely from the markings to illuminate the markings, particularly at night. The markings can be placed on any surface inside a vehicle, such as a gear shift know, door handle or steering column control stalk. Additionally, the light source can be placed in the roof of the vehicle, behind a steering wheel, or any other location having an unobstructed view of the markings.
