Abstract
A starting aid for high pressure sodium vapor lamps eliminates the need to mechanically connect an ignition wire to the lamp frame. The starting aid employs an ignition wire which is slidably clipped directly to the arc tube at one end and which is connected to a bi-metallic switch at the other end. The bi-metallic switch is mechanically and electrically connected to one power lead of the arc tube.
