What is the part number of the tail lights on a BMW E46?

The BMW E46 is the generation of the BMW 3 Series that was produced between 1999 and 2006, and is a popular model among enthusiasts known for its perfect blend of performance and style. When discussing BMW E46 taillight part numbers, it’s important to note that there are variations depending on the specific model year, body style (sedan, coupe, convertible, or wagon), and market region (U.S., Europe, or other international markets). BMW also offers different taillight configurations, including standard halogen, xenon, and late-model LED-enhanced taillights.

For the sake of clarity, I will provide some general information about E46 taillight part numbers, focusing primarily on the U.S. market and common configurations:

Sedan/Coupe/Touring (Wagon)

Halogen Tail Lights:
LEFT SIDE (DRIVER’S SIDE): common US market part numbers begin with “63 21 6 907 290”.

Right side (passenger side): Part numbers commonly begin with “63 21 6 907 291”.

Xenon Tail Lights (if equipped):
E46’s equipped with Xenon lamps usually have clear lens tail lamps to match the headlamp style. Part numbers vary slightly to reflect this design:
Left: Part numbers beginning with “63 21 6 907 289”.
Right: Part numbers beginning with “63 21 6 907 292”.

Convertible / Roadster

Convertible models may have slightly different part numbers for the taillights due to the unique trunk lid design and the possible presence of additional components associated with the folding roof unit. However, they usually follow a similar pattern to the sedan/coupe, but are designed specifically for convertible models.

LED Tail Lights (Late Model/Aftermarket):

Toward the end of E46 production, BMW introduced LED elements to the taillights for certain markets or models. These LED-enhanced taillights usually had different part numbers to reflect the newer technology. However, LED taillights were not factory standard on most models produced with the E46.

There is no specific “part number” for aftermarket LED conversions or upgrades, as these are not original BMW parts, but rather products from third-party manufacturers. Aftermarket suppliers have their own product codes or SKUs for such products.

The Importance of Part Numbers

When looking for a replacement taillight or upgrade, using the correct part number ensures the correct fit and compatibility for your particular E46 model. It is crucial to verify the part number against the vehicle’s VIN (Vehicle Identification Number) and date of manufacture, and to take into account any regional differences in lighting regulations.

It’s also worth noting that purchasing genuine BMW parts guarantees the best fit and quality, although they can be more expensive compared to aftermarket options. Aftermarket parts can save money and sometimes offer additional customization options, but they need to be carefully selected to ensure quality and compatibility.

In conclusion, while the specific part number for your BMW E46 Tail Lights will vary depending on a multitude of factors, understanding its basic structure and how to identify the correct part for your vehicle is key to maintaining or enhancing your vehicle’s lighting system. Be sure to consult an authorized BMW dealer, a trusted online database, or a verified aftermarket supplier for the most up-to-date and accurate part number for your specific E46 model.
