Diagram Ref No 3 

Fitted around the rear indicator lamp, the gasket creates a protective seal where the lighting assembly meets its mounting surface. It helps prevent water and dirt entering the surrounding area while maintaining a neat, properly seated installation.

An ideal replacement for perished or damaged original seals during classic Porsche maintenance, lighting repairs or restoration work.

What Does It Do?

The gasket provides a protective barrier around the rear indicator lamp, helping seal the gap between the lighting assembly and its mounting surface.

Its main purpose is to reduce the entry of rainwater, moisture and road dirt into areas surrounding the indicator.

It also provides a cushioning layer between the fitted components, helping protect their contact surfaces.

Why Is It Important?

Rear indicator lamps are constantly exposed to rain, road spray and changing weather conditions.

A sound gasket helps protect the lamp assembly and surrounding fittings from moisture-related deterioration.

A damaged or missing gasket may contribute to:

• Water collecting around the indicator assembly
• Condensation or moisture inside the lamp
• Corrosion around electrical contacts
• Dirt collecting behind the indicator
• Deterioration of surrounding mounting surfaces
• Poor seating of the lamp assembly

Why Do Rear Indicator Gaskets Fail?

Ageing is one of the main reasons original lighting seals deteriorate on classic Porsche models.

Years of exposure to sunlight, moisture and temperature changes can cause the gasket material to lose flexibility.

Common causes include:

• Rubber becoming hard or brittle
• Cracking and splitting with age
• Flattening from prolonged compression
• Shrinkage affecting the sealing surface
• Damage during indicator removal

When Should It Be Replaced?

Replace the gasket if it has become cracked, compressed, distorted or no longer seals correctly around the indicator.

Replacement is also advisable when restoring the rear lighting assemblies or removing the indicators for bodywork repairs.

Both sides should be inspected, as seals of a similar age may show comparable deterioration.

Installation Notes

Carefully remove the rear indicator assembly and inspect the existing gasket.

Clean the contact surfaces and remove accumulated dirt or old sealing material before fitting the replacement.

Position the new gasket evenly and ensure it is not twisted, trapped or displaced when refitting the lamp.

Secure the indicator without overtightening the fixings, which could damage the housing or compress the seal unevenly.
