ABSTRACT:
A probe light is provided with two power lines passed through a long tubular small diameter brass rod extended from a handle with a plug in socket connection to a power supply to a small cross sectional halogen lamp bulb socket for a small diameter halogen light bulb. The halogen light bulb used is a high intensity light bulb pulling relatively high amperage developing considerable heat. The tubular small diameter brass rod, that is bendable for use convenience, conducts heat away from the lamp bulb socket and the plug in leads of the lamp bulb are bent in a wave shape to insure good electrical contact through an extensive heat temperature range. The lamp bulb leads plug into internal openings in the two socket pins held within the lamp bulb socket with the socket pins being heavy duty pins also conducting heat away from the lamp bulb leads. A high temperature teflon sheath heat shrunk on the lamp bulb not only gives protection from high pressure shattering of the bulb but also diffuses the light to a more uniform illuminating source.
