A light unit (10) comprising a housing (12) securable to a mounting surface such that a lower end thereof is adjacent the lower surface of the mounting surface. A light module (13) is mounted within the housing (12) having a first lighting emitting surface provided on a lower end surface (40) of the light module (13) and a second lighting emitting surface provided on a side surface (44). The light module (13) is mounted for movement relative to the housing (12) such that the light module (13) is movable between a retracted position in which the first lighting emitting surface is exposed and the second lighting emitting surface is covered by the housing (12), and an extended position in which the second lighting emitting surface is exposed.
