Abstract
The present invention is directed to a fixture which is characterized by its ability readily to be lamped and relamped, notwithstanding the fixture is located at a position which is accessible only with difficulty. The fixture includes a socket which coacts with the terminals of a bulb of particular design to center the terminals and to enable electrical and mechanical contact to be effected by a simple inward movement of the bulb relative to the socket.
