BMW/MINI 41357267328
Overview & Operating Principle

The HEADLAMP ASSY is the complete front lighting assembly that provides the vehicle's primary road illumination and forward signalling functions, integrating within a single polycarbonate-lensed housing the low beam, high beam, daytime running light, position lamp, and direction indicator, with the specific light source technology — halogen, HID xenon discharge, or LED — determined by the vehicle's trim level and market specification. The optical system within each headlamp housing consists of a projector lens module or a parabolic reflector for each function, precision-formed to project a legally defined beam pattern with a sharp horizontal cutoff on the low beam that maximises road illumination ahead while preventing glare to oncoming drivers as required by ECE R112 and R123. On HID xenon assemblies an integrated ballast or an external ballast unit generates the 20,000V ignition pulse and regulates the 85V operating arc of the xenon burner, and the assembly incorporates a mandatory automatic headlamp levelling motor that adjusts the projector module angle in response to the ride height sensor signal. On matrix LED and adaptive headlamp assemblies, an LED driver control unit within the housing manages individual LED segment activation, turning off segments that would dazzle oncoming vehicles detected by the forward camera, effectively providing full high beam illumination without glare.

This unit — BMW/MINI 41357267328 — is manufactured to OEM-equivalent specifications: housing mounting point geometry and seal profile, lens outer surface form for gap and flush fit to the adjacent wing and bumper, reflector and projector optical geometry, levelling motor travel range and connector pinout, wiring connector positions and locking tab geometry, and ECE type approval compliance for the relevant market are matched to the original part. Supplied as a direct bolt-in replacement for standard fitment. Available wholesale from 8.5 USD, MOQ 10 pcs, production lead time 30-45 days.

Headlamp assemblies are replaced after impact damage that cracks the lens or housing, UV-induced lens hazing that reduces light transmission below ECE minimum intensity thresholds, moisture ingress through degraded housing seals that corrodes reflector coatings and bulb holders, and electrical failure of integrated LED driver boards or HID ballast units that are not separately serviceable. Always aim the headlamps correctly after any replacement — a headlamp aimed incorrectly after replacement dazzles oncoming drivers at low beam and reduces forward visibility at high beam, and is an immediate roadworthiness failure item at vehicle inspection.

Symptoms & Diagnostics
Visible crack, shatter, or missing section of the outer lens from an impact — a cracked lens is an immediate roadworthiness defect in all jurisdictions; water ingress through a cracked lens reaches the reflector coating within days in wet weather, permanently hazing the reflective surface and reducing beam output below ECE minimums even after the assembly is replaced.
Lens surface uniformly yellowed, hazy, or opaque from UV degradation — the polycarbonate UV protective coating has failed, reducing light transmission and scattering the beam pattern; a heavily hazed lens fails ECE photometric standards and produces a roadworthiness failure at vehicle inspection regardless of bulb or LED condition.
Condensation or water pooling inside the housing visible through the lens — the perimeter body seal has failed or the lens-to-housing bond has cracked; sustained internal moisture corrodes the reflector aluminium coating, oxidises bulb holders, and destroys LED circuit boards within a short period; a housing with condensation that does not clear within 48 hours of driving has a structural seal failure and requires replacement.
One or more lighting functions inoperative on an LED assembly after confirming correct fuse and relay condition — the integrated LED driver board for the affected function has failed; LED headlamp driver boards are not field-serviceable and the complete assembly must be replaced; on assemblies with BCM lamp monitoring, a specific fault code identifies the failed LED circuit.
Low beam pattern aimed incorrectly — beam too high dazzling oncoming traffic, or beam too low reducing forward visibility — the headlamp levelling motor or its gear mechanism has failed on a xenon or automatic-levelling LED assembly, holding the projector module at an incorrect angle; confirm by commanding the levelling motor via scan tool live data.
Headlamp assembly misaligned relative to adjacent body panels after a frontal impact — the housing mounting tabs or adjustment brackets have fractured, allowing the assembly to shift on its remaining fixings; a misaligned headlamp affects gap and flush to the bumper and wing, produces an incorrect beam aim, and allows water ingress at the displaced body seal.

Installation Tips
  1. Disconnect the negative battery terminal before removing any headlamp assembly — HID xenon ballasts retain a lethal charge of up to 20,000V for several minutes after the ignition is switched off; always disconnect the battery and wait a minimum of 3 minutes before handling any xenon ballast connector or burner; on matrix LED assemblies the LED driver circuits retain charge that can destroy the new assembly's driver board if connected while the vehicle supply is live.
  2. Remove the front bumper or wheel arch liner section as required by the vehicle-specific procedure to access all headlamp mounting bolts — most modern headlamp assemblies have one or two mounting points accessible only from behind the bumper fascia; attempting to remove the assembly without releasing all mounting points cracks the housing at concealed mounting bosses and distorts the lens frame.
  3. Transfer the levelling motor, ballast, and any separately mounted modules from the old assembly to the new unit only if they are confirmed serviceable and are not integrated into the new assembly housing — on HID systems the ballast is often mounted separately on the body behind the headlamp and connects to the new assembly via the existing harness; on LED systems verify which modules are integral to the new housing and which are supplied separately before beginning the transfer.
  4. Inspect the body aperture seal face and all wiring harness grommets for damage before fitting the new assembly — a corroded or deformed aperture seal face allows water ingress behind the new assembly, reaching the body cavity and potentially the headlamp housing interior through gaps at the rear; clean the seal face and apply butyl tape if the original seal is compressed or cracked.
  5. Confirm the replacement assembly is the correct market specification before installation — left-hand-drive and right-hand-drive headlamps have different asymmetric low beam cutoff angles that are not interchangeable; fitting the wrong-hand assembly produces a beam that dazzles oncoming traffic on the correct side while leaving the road edge unilluminated, and is a legal offence in all jurisdictions.
  6. Install the new HEADLAMP ASSY (BMW/MINI 41357267328), torque all mounting fasteners, reconnect all electrical connectors, reconnect the battery, and perform a full headlamp aim check and adjustment on a headlamp aiming screen or optical beam setter before the vehicle leaves the workshop — on xenon and matrix LED assemblies perform the levelling system initialisation via scan tool, and on vehicles with camera-based ADAS systems perform a front camera calibration if the headlamp replacement required bumper removal that disturbed the camera mounting position.
Tools: headlamp aiming screen or optical beam setter, OBD-II scanner with BCM and levelling system access, trim removal set, torque wrench, butyl tape for seal face repair, 3-minute wait timer for HID ballast discharge.
Frequently Asked Questions
Should both headlamp assemblies be replaced simultaneously when only one is damaged or hazed?
Replacing only the damaged or hazed unit is appropriate when the opposite assembly is in good condition and its beam output and pattern are confirmed correct on an aiming screen. However, on vehicles where both lenses show advanced UV hazing — typically above 8–10 years — replacing both simultaneously ensures matching beam colour temperature, intensity, and pattern on both sides, which is relevant for driver visibility and for the photometric balance required at vehicle inspection. A new high-output assembly paired with a heavily hazed opposite unit creates an asymmetric illumination pattern that the driver perceives as a fault even when both assemblies are individually within specification. ok.parts supplies headlamp assemblies individually and in left-right pairs at wholesale MOQ from 8.5 USD per unit.
Is BCM coding, adaptation, or ADAS calibration required after headlamp replacement?
Requirements depend on the technology level of the assembly. Halogen headlamps require no coding — reconnect and aim. HID xenon assemblies require a levelling system initialisation via scan tool on the first ignition cycle after replacement to set the zero reference position of the new levelling motor. Matrix LED and adaptive headlamp assemblies on premium vehicles require BCM variant coding via manufacturer-specific scan tool to register the new assembly's electronic module and enable all adaptive functions. On vehicles where the headlamp replacement required bumper removal, any forward-facing radar or camera for autonomous emergency braking, lane keep assist, or adaptive cruise must be recalibrated on a calibration target — this is mandatory regardless of headlamp technology level.
