A one-piece, molded plastic spring clip, which is substantially inverted U-shape in cross-section, has a bight portion including an opening receiving a screw threaded fastener to attach the clip to the rear surface of a lamp holder so that the screw threaded fastener does not extend from the clip through a headed flange portion of a lamp holder to provide a liquid conduit which could potentially short the lamp. The clip is provided with legs extending from either side of the bight and each leg has a pair of spaced, parallel wing portions extending outwardly from its associated leg to expand when inserted through the mounting plate. The wing portions provide vertical shoulders to seat the lamp holder on a vertical support in conjunction with a compressible coil spring provided on the opposite side of the mounting panel or vertical support between the headed flange and support to exert pressure on the clip shoulders against the rear of the mounting panel. A second non-compressible lamp holder is provided for the opposite end of the lamp on a second mounting panel. A one-piece, molded plastic spring clip is also provided for mounting the second lamp holder in a similar fashion, but is provided with flanges extending outwardly from the bottom of each leg, parallel to the bight portion so that the lamp will exert an axial force on the clip under the spring pressure of the compressible spring associated with the other lamp holder to clamp it to the front surface of the second mounting panel.

A protective shield is provided for preventing moisture from reaching electrical connections of a lamp inserted in a lampholder. The shield includes a waterproof cover part which fits tightly around the end of the lamp envelope and extends beyond the end of the lamp and a waterproof barrier part which prevents moisture from flowing into a junction between the lamp end and a lampholder in which the lamp is inserted. Preferably the cover part and the barrier part are integrally formed from a resilient material, and the barrier part surrounds the end of the lampholder.
