ABSTRACT:
A sealed beam lamp shock suppressing retainer ring grommet for quadruplicating lamp life.
The dual shocking suppression takes place as a result of the ductile rubberlike material and the cantilever load effect of the lamp on the free end of the grommet.
Additional features include weatherproof lamp electrodes, retainer ring and lamp grommet combined as one unit, external ease of changing the sealed beam lamps and a long retainer ring life.
