E46 Facelift Sedan/Wagon Halogen Headlights: Black ZKW vs Titanium AL

OEM numbers

Black-trim ZKW halogen: 63127165771 left/driver and 63127165772 right/passenger. Titanium-trim AL halogen: 63127165785 left/driver and 63127165786 right/passenger. Factory xenon and bi-xenon assemblies are separate part families and are excluded.

Supersession

63126910963 -> 63127165771 black ZKW left; 63126910964 -> 63127165772 black ZKW right; 63126910965 -> 63127165785 titanium AL left; 63126910966 -> 63127165786 titanium AL right. These are side- and trim-specific chains, not a halogen-to-xenon conversion.

Fitment

Confirm VIN production date from 09/2001, US/LHD sedan or wagon body, factory halogen equipment, left/right side, and black ZKW versus titanium AL appearance before ordering. Match the installed label, connector, mounting tabs, adjusters, bulbs/sockets and corner-lamp appearance. Do not substitute pre-facelift, coupe/convertible/M3, xenon/bi-xenon or RHD optics. Aim the completed lamps with the correct procedure.

Aftermarket options

Checked paths include OE-supplier ZKW black assemblies, exact-number Genuine BMW titanium assemblies, Dorman 1592259 for the black RH halogen branch, and condition-checked used OEM assemblies. Aftermarket halo/chrome pairs and HID conversions are not represented as equivalent replacements; confirm DOT/LHD beam pattern, trim color and included bulbs, sockets and adjusters.

Before you buy

This guide covers only US/LHD E46 sedan/wagon cars built from 09/2001 with factory halogen lights. Match side and black ZKW versus titanium AL trim; factory xenon, other body styles, earlier cars and RHD optics use separate paths. Seller price/availability is a dated observation. Inspect used assemblies and professionally verify headlamp aim after installation.
