Will this LED driver board fit my BMW X3 F25 tail light?

These boards are designed specifically for BMW X3 F25 tail lights produced between 2011 and 2015. They correspond to the factory part numbers 63217217311 through 63217217314 and the Valeo reference b003809.2, ensuring physical and electrical compatibility with those housings.

• Compatible part numbers: 63217217311, 63217217312, 63217217313, 63217217314
• Direct replacement for Valeo b003809.2 LED driver
• Voltage: 12V, Wattage: 3W — matches original specifications

How easy is installation for a DIY mechanic?

Installation is straightforward for anyone comfortable accessing the rear tail light assembly and removing the old driver board. No special programming or coding is required; these boards are plug-and-play replacements when matched to the correct part number and socket orientation.

• Remove tail light housing to access the driver board
• Unplug the original Valeo board and insert the FBULWSEC replacement
• No ECU coding typically needed if the part numbers match

What comes in the package and what are the product specs?

The product ships as a 4-pack of LED driver boards so you can service both tail lights and retain a spare. Each board is rated at 12 volts and consumes 3 watts, designed to replicate the factory driver's electrical load and fit.

• Package: 4 x LED driver boards (LED chips)
• Electrical: 12V nominal, 3W per board
• Intended application: rear tail lights for BMW X3 F25 (2011–2015)

Will replacing the board fix common tail light failures?

If the tail light issue is caused by a failed LED driver (flicker, partial outage, or total rear lamp failure), swapping in a new driver board often resolves the problem. However, this replacement addresses driver-chip faults only; wiring, connectors, or LED array damage may need separate repair.

• Fixes driver-related flicker and outage when matched correctly
• Does not repair physical LED lens or lamp housing damage
• Check wiring and connectors if symptoms persist after replacement

Who is this for: This 4-pack is intended for BMW owners, independent mechanics, and restoration shops working on X3 F25 vehicles from 2011 to 2015 who need a reliable, direct-fit replacement for Valeo b003809.2 LED driver failures. FBULWSEC parts include a one-year warranty, making the kit a practical option for anyone seeking a cost-effective repair without replacing the entire tail lamp assembly.
