For the Rolls-Royce Ghost (RR21), the part number 5A8FE8602 (often found as 63215A8FE85 or 63215A8FE86) refers to the LED Rear Tail Light Assembly for the latest generation (2021–Present).

In 2026, these are high-tech, sealed units that feature the distinctive “lozenge” light signature. They are available in two primary finishes: Chrome (standard) and Black Badge (darkened).

1. Component Details & Identification

• Part Number (Left): 63215A8FE85 (Internal code: 5A8FE8502)

• Part Number (Right): 63215A8FE86 (Internal code: 5A8FE8602)

• Application: Rolls-Royce Ghost (RR21) and Ghost Extended (RR22).

• Lighting Technology: Full LED (no replaceable bulbs).

2. Technical Features

• Dynamic Lighting: The RR21 tail lights feature a startup “welcome” animation and integrated dynamic turn signals.

• Surface Design: The lens is designed to appear as a solid “block of light” with no visible individual LEDs, maintaining the Ghost’s minimalist aesthetic.

• Sealed Unit: Unlike the previous generation (RR4), these units are fully sealed. If the LED strips flicker or fail, the entire assembly must be replaced.

3. Black Badge vs. Standard

The part number you provided is often associated with the standard chrome-trimmed version. However, for 2026, many owners are retrofitting the Black Badge versions.

• Standard: Features a bright chrome inner housing.

• Black Badge: Features a deep “Black Chrome” or smoked internal finish. Installing Black Badge lights on a standard Ghost is a popular “Plug-and-Play” upgrade, though it typically requires both sides to be changed simultaneously to match.

4. Installation & Safety Note

• Access: To replace the Ghost RR21 tail light, you must remove the interior trunk lining on the corresponding side to access the three 10mm nuts holding the unit in place.

• Weather Seal: The unit comes with a factory-applied foam gasket. If you are buying a used unit, ensure this gasket is not compressed or torn, as water ingress will damage the vehicle’s rear electronic modules (located directly below the light housing).

• Coding: While the lights usually work immediately upon installation, a “Module Replacement” reset via ISTA is recommended to ensure the voltage monitoring system correctly identifies the new LED load and prevents “Bulb Out” dashboard warnings.

5. Troubleshooting for 2026

If you are replacing a light due to a “Lighting Malfunction” error but the lens is not cracked, check the Rear Body Domain Controller (BDC). In 2026, we have seen instances where moisture in the trunk (due to a clogged sunroof drain) shorts out the connector pins, making a perfectly good tail light appear dead.
