Clear Tail Light Part Number for Porsche 991: Complete Guide

Many Porsche 991 (2012–2019) owners seek to upgrade their tail lights to a clear lens design for a modern, aggressive look. Whether you want OEM Porsche clear tail lights or an aftermarket set, knowing the exact part number is essential. This guide lists the factory part numbers for clear tail lights on the 991, explains the differences between red and clear variants, and covers aftermarket options. You'll also learn how to verify compatibility and what to expect during installation.

Understanding the Porsche 991 Tail Light Options

The 991 generation includes coupes (Carrera, Carrera S, etc.), cabriolets, and Targa models, plus high-performance variants like the Turbo and GT3. Tail light designs vary by model year and trim. Factory tail lights typically feature a red lens with clear sections for turn signals and reverse lights. However, Porsche offers a clear tail light option (often referred to as "clear lenses" or "European style") that gives the rear a lighter, more contemporary appearance.

Factory Clear Tail Lights vs. Red/Clear

From the factory, most 991s have tail lights with predominantly red lenses. The clear tail light option, available as a factory-installed extra on certain models, uses a clear outer lens with red LED inner elements. This design creates a distinctive look, especially on lighter-colored cars. The part numbers differ between these variants, and using the wrong one can lead to fitment issues or electrical mismatches.

OEM Part Numbers for Clear Tail Lights

Below are the official Porsche part numbers for clear tail lights on the 991. These are for the complete assembly (left and right sides, including the outer tail light, inner decklid light, and sometimes the light module). Always verify with your dealer as the exact number may depend on your specific model and production date.

• Left Outer Tail Light (Clear): 991 631 171 00
• Right Outer Tail Light (Clear): 991 631 172 00
• Left Inner Tail Light (Decklid, Clear): 991 631 173 00
• Right Inner Tail Light (Decklid, Clear): 991 631 174 00

For vehicles with the LED tail light option (standard on some 991.2 models), the part numbers may start with 991 631 295 xx and 991 631 296 xx. Check your car's VIN for accurate compatibility.

Aftermarket Clear Tail Light Options for 991

If OEM pricing is too high or you want a different design, reputable aftermarket brands offer clear tail lights for the 991. These often feature smoked or clear lenses, sequential turn signals, or darker housings.

Popular Brands and Compatibility

Well-known aftermarket manufacturers include Depo, Spyder, and OEM-quality replicas. Most aftermarket units are plug-and-play, but some require coding to avoid error messages. For example, aftermarket LED tail lights may need a load resistor or a software update to work with the car’s CAN bus system.

Key considerations:

• Fitment: Ensure the lights are specifically designed for the 991 (not 997 or 992).
• Lighting Function: Aftermarket lights may use non-LED bulbs for turn signals or reverse lights, which can cause hyperflashing. Some kits include resistors.
• Legal Compliance: Clear tail lights must meet DOT or ECE regulations, depending on your location. In the US, aftermarket lights may not be street-legal if they lack proper reflectors or brightness levels.

Choosing Between OEM and Aftermarket

OEM Porsche clear tail lights are the easiest for peace of mind—they fit perfectly, match the car’s electrical system, and retain the factory look. Aftermarket options are cheaper (often $400–$700 for a full set versus $1,200+ for OEM) and offer unique styles like smoked lenses or dynamic turn signals. However, aftermarket lights can have variable quality and may not last as long. For most daily drivers, the OEM route is recommended. If you want a custom look and are willing to troubleshoot potential issues, aftermarket can be a valid choice.

How to Verify Your Part Number

Before ordering, confirm your car’s exact model and year. The easiest way:

1. Check your current tail light lens—on the backside of the assembly, there is usually a stamped part number.
2. Use your Porsche VIN with an online parts catalog or ask your dealer’s parts department.
3. Note that clear tail lights were not standard on all 991s. If your car originally had red lights, simply ordering the OEM clear parts listed above should work, but wiring differences exist between early 991.1 and later 991.2 models.

Installation Considerations

Replacing tail lights on the 991 is a straightforward DIY job.

• Tools needed: Trim removal tools or a flathead screwdriver (wrapped in tape), Torx T20 or T25 driver, and possibly a 10mm socket.
• Steps: Open the trunk or rear hatch. Remove the trim panels to access the tail light bolts. Disconnect the wiring harness. Unbolt the old light and remove it. Install the new light in reverse order.
• Warning: Do not overtighten the bolts; use a torque wrench set to about 6 Nm.

If you are switching from red to clear tail lights, you might need to code the car to recognize the new LED modules. Some 991s (especially .2 models) require a PCM software update to prevent error messages. A Porsche specialist or dealer can perform this coding.

Final Recommendation

For most 991 owners, the best choice is to buy OEM clear tail lights using the part numbers listed above. They offer guaranteed fit, reliability, and avoid potential coding headaches. If budget is a concern, a high-quality aftermarket set from a trusted brand like Depo can provide a similar look at half the cost—but be prepared for possible fitment adjustments and resistor installation. Always purchase from a reputable seller who offers a return policy. Verify part numbers before purchasing to ensure a proper match to your 991.
