Installation Guide

Installing the Van Wezel 0647934 Rear/Tail Light is straightforward for those familiar with BMW body panels. Follow these steps:

1. Remove Existing Assembly: Use a flathead screwdriver to detach the rear light housing from the car’s trunk panel. Disconnect the electrical connector and carefully lift the unit.
2. Prepare New Unit: Inspect the new assembly for any shipping damage. If necessary, replace the bulb with an OEM or equivalent LED module.
3. Connect Wiring: Plug the 4‑pin connector into the vehicle’s harness, ensuring a snug fit to avoid intermittent faults.
4. Mount Assembly: Align the new unit with the mounting brackets on the trunk panel. Secure it using the original screws or the provided fasteners.
5. Test Functionality: Before closing the trunk, activate each light function (brake, reverse, turn signal) to confirm proper operation.

Compatibility & Alternatives

The Van Wezel 0647934 is often compared with other aftermarket options such as the ABAKUS 444‑1302R‑UQ series. While both provide similar functionality, Van Wezel’s direct fit design eliminates the need for additional adapters, making it a preferred choice for DIY enthusiasts.

Maintenance Tips

• Regular Inspection: Check the lens for cracks or scratches every six months to maintain optimal light output.
• Cleaning Procedure: Use a microfiber cloth with mild soap and water. Avoid abrasive cleaners that can damage the polycarbonate surface.
• Bulb Replacement: If using incandescent bulbs, replace them at the first sign of dimming. LED modules should be replaced only if they fail to light.
