Abstract
Abstract The lamp holder includes a collar which is captured in a groove provided in the reflector section of a lamp housing by a cupshaped lens overlying and bonded, preferably ultrasonically, to the reflector section. Spring fingers extending from the collar of the lamp holder fit into slots provided in a barrel section of the lamp housing. The spring fingers have multiple bends forming two knee-like portions, one adapted to hold an indicator lamp and the other extending through slots provided in the barrel section, when an indicator lamp is installed. The latter knee-like portion engages the inside surface of the casing into which the lens assembly is installed and establishes electrical contact between the lamp and the casing.
