• Compatibility with Halogen R10W Lamps: The unit is engineered for use with standard halogen bulbs rated at 10 W, providing bright illumination while maintaining energy efficiency.

Vehicle Compatibility Matrix

The housing has been certified to fit a broad spectrum of vehicle models. Below is an overview of the most common applications:

Installation Overview

The installation process is straightforward, requiring only a few basic tools:

1. Remove Existing Housing: Unscrew the current licence plate light housing using standard automotive screwdrivers or socket wrenches.
2. Clean Mounting Surface: Ensure the mounting area is free of rust, paint flakes, and debris to guarantee a secure fit.
3. Position New Housing: Align the HELLA 9BG 121 587‑031 with the mounting points. The integrated gasket should sit flush against the vehicle body.
4. Screw in Place: Tighten all fasteners to the manufacturer’s torque specifications, typically around 10–12 Nm for most models.
5. Insert Lamp and Lens: Install the halogen R10W bulb into the lamp socket, then secure the lens onto the housing. Verify that the light is centered and free of obstruction.
6. Test Functionality: Activate the vehicle’s rear lighting circuit to confirm proper illumination and electrical continuity.

Electrical Compatibility

The housing supports standard automotive low-voltage systems (12 V DC). It is compatible with both single-phase and dual-phase wiring configurations commonly found in commercial fleets. The internal design includes a dedicated contact point for the lamp socket, ensuring reliable electrical connection without additional adapters.

Compliance & Certification
