Up for sale is this This dome light / trunk light, fits classic 900's as a dome light, pre 1988 cars only, and fits 900 / 9000 as a trunk light for the entire production run.  Unit is in good shape, no cracks.  This unit is frequently broken when attempting to change the bulb.  If pulled from the wrong direction or over tightened with the small torx bit, the tangs snap off, and there is no way to put the lamp back into the headliner or trunk mat.  This one is good used, and still quite nice, tangs are all in-tact.
