Description

Replaces BMW part number 54121884483 to support the dome lights on E30 coupe (likely sedan as well, but not convertible). If your dome lights are dangling in the fabric of your headliner, its because the 30+ year old plastic bracket has become brittle and broken. Printed in PETG but ASA or ABS would be fine too.
