Abstract
Abstract An illumination device includes a lamp assembly enclosing a lamp bulb and providing electrically conductive tabs extending outward from the sidewalls of the lamp assembly and connected in electrical communication with the lamp bulb, and a socket adapted for mounting in a hole in a transparent panel. The socket includes contact spring locking means consisting of a finger portion extending outside of the socket and a bowed spring portion connected to such finger portion and fitting into recesses formed in the inner walls of the socket. The finger portions tightly lock into grooves formed on opposite sides of the panel hole so as to lock the socket in the panel. The lamp assembly is adapted to be inserted into the socket and locked into place by pressing the lamp assembly with its tabs against the socket and rotating such lamp assembly relative to the socket to compress the bowed portion and permit such tabs to pass over center and lock into place in the recesses provided in the socket.
