This is a purpose-built, dual colour LED ambient light door trim kit designed specifically for the BMW 3 Series F30 sedan and F31 touring produced between 2012 and 2018. The kit replaces all four interior door trim strips with illuminated units that emit either orange or blue light, giving the cabin a factory premium feel that rivals higher-specification BMW models equipped from the factory with ambient lighting packages. Each strip is manufactured to a 1:1 mould of the original BMW door trim profile, meaning the fitment is precise and the finished result looks factory installed rather than an afterthought. The trim body is constructed from ABS and PC plastic with a TPU anti-scratch surface treatment, and the embedded LED lamp beads number 234 across the full set of four strips. The wiring harness uses gauge-grade German standard cable rated to 200 degrees Celsius, supplied in two sections: a main line and a door panel line. Buyers who do not have the factory ambient light package installed connect the unit via the included 2-pin connector. The kit ships with all four illuminated door trim strips, two connection wire sets, one screw pack, and a printed installation instruction sheet.
Key Features and Benefits
The dual colour function allows the driver to select between orange and blue illumination, providing two distinct cabin moods from a single installed kit. The 234 embedded SMD LED lamp beads across all four doors produce bright, even illumination along the full length of each trim strip. The trim shell is moulded to exact OEM dimensions using a 1:1 mould opening design, eliminating gaps or misalignment during installation. ABS and PC construction with TPU anti-scratch treatment protects the trim surface from contact wear over time. The wiring harness is built to gauge-grade German automotive wiring standards and is rated to withstand 200 degrees Celsius, making it suitable for the thermal conditions inside a car door cavity. The door bowl area includes a double colour adjustment function, allowing the lit zone around the door pull to be set independently. The kit works on F30 and F31 vehicles that were not factory fitted with ambient lighting by using the 2-pin connection method, meaning ownership of the factory light package is not a prerequisite. The complete four-door coverage means all passengers benefit from consistent ambient illumination rather than front doors only.

Installation Notes and Special Functions
The trim strips replace the existing door trim panels directly, using the original mounting points via the 1:1 mould design. The two-part wiring harness routes through the door cavity: the door panel line connects at each door and the main line runs to the vehicle power source. On vehicles without the factory ambient light package, the included 2-pin connector is used in place of the factory plug. Polarity must be observed during connection; if LEDs do not illuminate on first attempt, reverse the positive and negative connections on the relevant connector. Brightness level at standard connection is noted by verified buyers as high; if brightness reduction is required, inline resistors can be added to the circuit by the installer. A user manual PDF is available from the supplier. Installation requires basic DIY automotive electrical knowledge including door card removal and cable routing. Professional installation is recommended for buyers not experienced with automotive electrical work or door panel removal on BMW vehicles.
