Original BMW Luggage Compartment Light for BMW E21, E36, E28, E34, E32, E31, and Z3 (1979–2002)

Original BMW part 63-31-1-378-089 is the luggage compartment light that illuminates the trunk on a long run of BMW 3 Series, 5 Series, 7 Series, 8 Series, M3, and Z3 models from 1979–2002. It weighs only 14 g, and BMW has produced this number since October 1985. It is made in Hungary and sold as a single piece. A trunk light switches on when the lid opens so you can see the load floor at night.

Original BMW Parts carry a 24-month parts warranty.

This number replaced the earlier 63-31-1-366-833, and BMW rates the change as exchangeable retrospectively, so 63-31-1-378-089 can go into cars that left the factory with the older lamp. That makes it a straightforward single-number choice across several generations: the E21 and E36 3 Series, the E28 and E34 5 Series, the E32 7 Series, the E31 8 Series, and the Z3. BMW lists the same light for the Z3 roadster and the sedan models shown here.
