Purpose and compatibility for BMW F20/F21 LCI M140i

The presented headlight is dedicated to the front left side of the BMW 1 Series F20/F21 generation facelift (LCI) in the M140i version. The design, based on factory BMW solutions, guarantees a proper fit to the shape of the bumper, hood, and fender, which translates into stable mounting and correct beam geometry.

As an OEM component with LED technology, the headlight works with factory electrical installations and lighting control units, which facilitates installation and reduces the risk of errors in onboard systems.

LED technology and optical characteristics

The headlight uses LED technology, which provides bright, uniform illumination of the front lane and a clear cut-off line. The use of LEDs promotes stable light color, good visibility of signs and obstacles, and fast light activation.

The optical system has been designed to the BMW M140i specification, ensuring that the light beam distribution is adapted to the suspension characteristics and body geometry of this model. This is important both for driving comfort and for meeting homologation requirements.

Exterior appearance and Black Line finish

The headlight stands out with its black interior finish (Black Line), which gives the front of the car a more dynamic, sporty look without compromising lighting functionality. The dark internal elements create a visually cohesive set with M styling packages and other black body accessories.

The transparent headlight lens exposes the characteristic LED layout, and the contrast between the black background and the optical elements highlights the modern design of the facelifted 1 Series. This solution is particularly valued by users who want to maintain the original BMW look while enhancing its sporty character.

Condition, functionality, and service application

The headlight is used, making it an attractive cost-effective alternative to new components while maintaining the manufacturer's original specification. It can be used both as a replacement for a damaged headlight after a collision and during the staged reconstruction of the vehicle's front end.

Thanks to its factory design and proper positioning on the vehicle, this component performs well in professional body and paint repairs, where maintaining the original body line and correct operation of lighting systems is crucial.
