Finding the Correct Headlamp for a BMW E46

There is no single fitment for every E46. Match the year, body style, market and lighting equipment in a vehicle-specific catalog, preferably using the VIN, and verify the part number.

Do not assume they interchange. Body-specific shapes and mounting details can differ, so check the exact vehicle in BMW parts information before ordering.

If the bulb is the failed component and the assembly is serviceable, a bulb replacement may be appropriate. Confirm the specified bulb type and inspect the connector and housing for damage.

Not automatically. Replace the failed or damaged part when compatible, then check beam aim and consider whether aging or mismatched lamps affect the light pattern.
