Grommet only — light and wiring sold separately.
The Peterson B426-18 4-inch round light grommet mounts a compatible round lamp flush in a panel. Use it when replacing the mounting grommet around a stop, turn, tail or accessory light, rather than replacing the entire lighting assembly.
The black PVC grommet fits a 4.50-inch-diameter mounting hole. The 4-inch size refers to the lamp, not the panel opening; check both before ordering a replacement.
| Feature | Benefit |
|---|---|
| Separate mounting grommet | Replace the mounting component while retaining a serviceable compatible lamp. |
| Round flush-mount design | Seats a compatible 4-inch lamp in the panel opening. |
