?cket 6170 LIGHTING FIXTURE A lighting fixture for attachment to the ceiling of public transportation vehicles such as subway cars, buses, aircraft, or the like includes a light transmitting cover assembly which is particularly adapted to retain and back light low cost sheets of advertising material, such as material printed on vellum or thin paper, while also accommodating conventional car cards or transparencies. The fixture further provides a pivotal mounting arrangement along one marginal edge which provides ease of installation with vehicles of varying ceiling contour. |
