ABSTRACT:
An impact and corrosion resistant lamp holder having a lamp housing formed of electrically non-conductive elastomer. The lamp housing includes a lamp receiving portion and external electrical contacts. A first electrically conductive pathway is provided leading from the lamp receiving portion to a first of the electrical contacts. A second electrically conductive pathway is provided leading from the lamp receiving portion to a second of the electrical contacts. The first and the second electrically conductive pathways are formed of electrically conductive elastomer and electrically conductive metal. The lamp housing eliminates any metal to metal contact between the lamp housing and its inserted lamp, thereby significantly reducing transmittance of vibrations to the lamp.
