Abstract
Abstract An auxiliary brake lamp and night lamp mounted on the deck above the trunk and behind the car's rear seat. The lamp has an opaque, hollow light seat which is made with two penetrating flutes for engaging two transparent boards in its upper part. A PC board is housed in the light seat beneath both penetrating flutes and has two rows of small bulbs which emit light into the penetrating flutes and the lower edges of the engaged boards. One of the boards is crimson, flat and has a plurality of parallel grooves on its back side which causes light passing through the board's edge to collectively form a warning on its front side. The second board is colorless, flat and has a plurality of parallel grooves on its back side which causes light passing through the board's edge to form a decorative pattern on its front side.
