Abstract: A vehicle rear signal light assembly (16) of the high mounted type is mounted within a rear roof header (18) of a roof panel (12) to shine a light signal from a source (40) through a lens (38) aligned with an opening (36) in an obscuration band (34) of an upper rear window edge portion (28) covering an outwardly opening flanged construction of the roof header. The signal light assembly (16) by utilizing existing vehicle structure does not intrude into the interior space of the occupant compartment either at its storage shelf or its headroom. Different embodiments of the signal light assembly (16,16a,16b) provide a brake signal, turn signals, and both brake and turn signals. The light source (40) may be either an electric bulb that shines through a lens (38) or one or more light emitting diodes (56) that shine through the lens which is aligned with the opening (36) in the obscuration band (40) through which the signal shines.
