2009-2016 Nissan GT-R Tail Light: Failures, Upgrades, and Bumper Removal Guide

Vehicle Generation and Part Changes: 2009-2014 vs. 2015+

The most important factor when buying a tail light for a Nissan GT-R is the model year. There was a significant design change starting in 2015.

• 2009-2014 Models: These vehicles are equipped with the classic dual-ring LED tail lights. The OEM part number for the left (driver's side) is 26555-KB50A and the right (passenger's side) is 26550-KB50A.
• 2015-2016 Models: These vehicles feature an updated design with a continuous LED light strip, often called the "lightning bolt" or "halo" style, for a more modern look. The part numbers for these are different (e.g., 26555-62B1A for the left side).

While the newer 2015+ style lights are physically compatible with the older 2009-2014 models and are a popular cosmetic upgrade, the parts are not a direct one-for-one swap without considering wiring adapters that may be needed for full plug-and-play functionality. When purchasing a used part, it is essential to verify which style you are buying.

Known Issues and Symptoms of Failure

The GT-R's tail lights are generally reliable, but like any modern electronic component, they can develop issues. Failure is rarely a complete blackout; more often, you will notice one of the following symptoms.

Condensation or Moisture Inside the Lens

The most common complaint is fog or water droplets forming inside the tail light housing. This happens when the seal between the lens and the rear housing degrades, or through the breather vents during extreme temperature swings. While a small amount of light fog that disappears quickly may be normal, persistent moisture can damage the LED circuit boards and chrome reflectors over time.

Individual LEDs Burning Out

The tail light is composed of multiple LEDs. Over time, one or more of these individual diodes can fail, creating a broken or incomplete light ring. This is not repairable by replacing a single "bulb." Since the tail light is a sealed unit, a partial failure of the LEDs requires replacing the entire assembly.

Cracked or Damaged Housing

Physical damage from impacts is a common reason for replacement. A crack in the lens or housing will allow water to enter freely, leading to rapid failure of the internal electronics. Even a small hairline crack can compromise the seal and cause condensation issues.

Complete Electrical Failure

Though less common, the entire tail light can stop working. This could be due to an internal circuit board failure, a bad wiring harness, or a corroded connector plug. Before replacing the unit, it's wise to check the vehicle's fuses and test the connector with a multimeter to ensure it's receiving power.

Buying a Used 2009-2016 GT-R Tail Light

Purchasing a used OEM tail light can offer significant savings over a new part. However, a thorough inspection is critical to ensure you get a quality component.

• Inspect the Lens: Check for any cracks, deep scratches, or hazing. Hold the light up to a light source to spot fine hairline cracks that could cause leaks.
• Check the Housing: Examine the black plastic housing on the back for cracks or damage, especially around the mounting studs. Ensure all mounting studs are intact and not broken off.
• Look for Signs of Moisture: Check for any water lines, mineral deposits, or a foggy film on the inside of the lens. This indicates the light has had a leak in the past and may have underlying electronic damage.
• Verify the Connectors: Look at the electrical connector pins. They should be clean and free of any green or white corrosion.
• Confirm the Style: Double-check whether you are buying the 2009-2014 ring style or the 2015+ lightning bolt style to ensure it matches your vehicle or your upgrade plans.

Replacement Information

Replacing the tail light on a Nissan GT-R is a complex task for a novice mechanic due to one major step: the rear bumper must be removed to access the tail light mounting bolts.

Tools Required:

• Socket set (8mm, 10mm, 12mm)
• Panel clip removal tool
• Phillips screwdriver
• A soft blanket or mat 🎬 See this 7-step guide for a professional tail light installation. to place the bumper on

1. Open the trunk and remove the plastic trim and carpeted liners to access the bolts and wiring inside.
2. Remove the clips and bolts securing the bottom of the bumper and the rear diffuser.
3. Remove the screws and clips inside each rear wheel well.
4. Disconnect any wiring for license plate lights or backup cameras.
5. With a helper, carefully pull the bumper away from the body, releasing the clips on the sides.
6. With the bumper off, you can now access the 10mm nuts that hold the tail light assembly to the bumper.
7. Installation is the reverse of removal. Test all light functions before fully reassembling the bumper.

Some experienced mechanics suggest it's possible to only partially drop the bumper to gain access, but full removal is the recommended procedure to avoid scratching the paint.

Recalls and Technical Service Bulletins (TSBs)

As of late 2023, there are no specific safety recalls or widespread Technical Service Bulletins (TSBs) issued by Nissan or the NHTSA for failure of the tail light assemblies on the 2009-2016 Nissan GT-R.
