Function and Common Faults

The third brake light (high-mount stop lamp) improves visibility to following traffic and complements the left/right brake lamps. It typically uses LEDs or a bulb assembly depending on version. Common reasons for replacement include impact or body damage (cracked lens), LED failure, connector corrosion, wiring faults, and moisture ingress that can cause short circuits or intermittent operation. In this specific unit there is a slight central crack in the lens but no fogging—cosmetic damage that may not affect function immediately but can allow dirt or moisture over time.

How Often It Fails

There is no fixed replacement interval for a third brake light; when intact it can last the vehicle’s lifetime. Failures are usually event-driven (accident damage, water ingress, or electrical faults). Routine checks during service will reveal non-functioning stop lamps, cracked lenses, or corrosion.

Replacement Procedure (Overview)

Suitable for experienced DIYers and professional mechanics. Typical replacement steps:

1. Open the tailgate and remove the interior trim panel to access the high-mount brake light assembly. Use trim tools to avoid damaging clips.
2. Locate and remove the retaining screws or nuts holding the lamp (fastener type may vary—Philips/Torx or socket set may be required).
3. Carefully pull the lamp assembly out through the tailgate aperture and disconnect the electrical connector(s).
4. Install the replacement unit, connect the electrical plug, and secure with the original fasteners. Ensure the wiring is routed without pinching.
5. Test the brake lamp operation (press brake pedal or use a second person) before refitting the trim. Reinstall the trim panel and verify all fasteners are secure.

Installation Recommendations

• Work on a cool, dry vehicle and keep the work area clean to prevent dirt entering the tailgate cavity.
• Use appropriate trim removal tools to avoid breaking plastic clips.
• Check connector pins and wiring for corrosion or damage; clean or repair as necessary before final assembly.
• Use correct fastener torque where specified and ensure the lamp sits flush to the body to maintain water sealing.
• After installation, verify operation of all brake lights and, if applicable, the centre stop lamp warning in the vehicle’s instrument cluster.

Why This Part Usually Fails

Most failures are caused by physical damage from rear impacts or tailgate handling, water ingress through a cracked lens or degraded seals, and electrical issues such as connector corrosion or LED component failure. Even a small crack, like the one present in this unit, can progressively allow moisture and dirt to enter and shorten service life.

Notes For Buyers

Part numbers 9681704280 and 6350EY are commonly used to identify this lamp when searching online or in parts catalogs. Confirm fitment visually on your vehicle (Peugeot 308 SW T7 tailgate high-mount lamp position) before installation.
