Lamp only — mounting grommet and wiring plug are separate selections.
The Peterson M163R is a five-diode, 2.5-inch round LED light for red clearance and side-marker applications. Its integrated PL10 receptacle connects to a matching two-prong lighting plug, while the grommet-mount body fits a compatible recessed installation.
Use this PC-rated lamp where the lighting layout calls for combined clearance and side-marker service. That dual function depends on correct mounting: select the 143-18 grommet for the PC-rated installation rather than assuming any 2.5-inch grommet is equivalent.
| Feature | Benefit |
|---|---|
| PC-rated design | Can serve both clearance and side-marker functions when correctly mounted. |
| PL10 receptacle | Connects to the matching two-prong plug without a permanently attached lamp lead. |
| Grommet mounting | Allows replacement of the lamp within a compatible recessed mounting arrangement. |
