What This Product Does
This gasket fits around the third brake light to maintain the seal between the lamp and its mounting area. It is intended for cases where the original gasket has deteriorated but the lens, housing and lighting components remain suitable for continued use.
Functions
- Replaces a cracked, compressed or degraded lamp gasket
- Helps seal the third brake light against its mounting surface
- Allows the existing brake light assembly to remain in place
- Supports correct seating of the lamp within the rear bodywork
Technical Details
- Product reference: 99663105007G
- Associated additional brake light reference: 99663105007
- Application context: additional brake light with equipment code M602
- Brand: OE Match
- Installation type: slip-on replacement gasket
- Installation typically takes around five minutes and requires no specialist tools. Instructions available.
Symptoms of Fault
- Visible cracking, splitting or hardening of the original gasket
- A flattened seal that no longer follows the lamp housing evenly
- Gaps between the brake light and its mounting surface
- Moisture staining or dirt collecting around the lamp edge
- Condensation associated with a deteriorated lamp seal
Why Replacement Matters
Age, ultraviolet exposure and repeated temperature changes can cause the original gasket to shrink or lose flexibility. Renewing the seal helps the brake light sit correctly and reduces the need to replace a complete, functioning lamp solely because its gasket has deteriorated. Inspect the lens, housing, electrical operation and mounting area before installation, as this gasket will not correct failed bulbs, LEDs, wiring or a damaged lamp assembly.

OEMatch 3rd Brake Lights components are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable. Third brake lights are high-mounted stop lamps that improve rearward visibility during braking and help reduce the risk of rear-end collisions on Porsche models, restoring both safety and visual balance.
Available Types- LED upgrade modules
- Smoked and clear lens finishes
- Replacement high-level stop lamp assemblies with wiring harness
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original 3rd brake lights.
OE (Original Equipment) refers to parts matching original specifications for the 3rd brake lights and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM 3rd brake lights engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch catalogues thousands of Porsche lighting references, including a large set of part numbers and OE cross-references, and continues to develop new lines to support maintenance and restoration across Porsche generations.
Benefits Include- Restores optimal brake signalling and improves visibility to following traffic
- Helps maintain compliance with vehicle inspections and road-safety requirements
- Offers LED and finish options to suit restoration or modernisation projects
- Burnt-out bulbs or failed LED modules
- Cracked or UV-faded lenses allowing light loss
- Water ingress leading to corrosion or condensation
- Damaged wiring or connector faults from vibration or impact
A functioning third brake light is a simple but important safety item on any Porsche. Timely replacement restores clear signalling to following drivers, reduces the likelihood of inspection failures and preserves the rear styling of the vehicle. Choosing a correctly matched unit supports reliable operation and avoids unnecessary modification to the bodywork or wiring.
Advantages- Direct-fit options that match mounting points and harness connections
- LED upgrade choices for improved longevity and light response
- Weather-sealed assemblies to limit moisture ingress and corrosion
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use new fasteners where specified.
