Lamp only — mounting grommet and wiring plug are separate selections.
The Peterson M817C-7 Lumen X LED backup light supplies white reverse lighting through a clear lens. This seven-diode model uses the nominal 4-inch round grommet-mount format and a 12 V electrical supply.
The housing incorporates an AMP receptacle angled at 30 degrees and sealed with silicone. Match the lamp to the correct AMP plug and mounting grommet; an otherwise similar PL3 lamp uses a different connection.

| White backup output | Provides the required light function for a compatible reverse-light installation. |
