  • Headlight mounting apparatus
    Patent number: 5613765
    Abstract: A headlight mounting apparatus for a headlight having a bulb mounted therein. The subject headlight mounting arrangement has a mounting portion integral with the headlight, a retaining mechanism and associated hardware, and a grommet arrangement of unique cross-sectional configuration which alters the frequency of vibration to a value significantly less than the natural frequency of vibration of the headlight bulb filament. This arrangement reduces bulb failures caused by shock experienced during vehicle/machine operation.
