ABSTRACT:
A light emitting diode (LED) retrofit lamp with locking swivel mount that mounts into a threaded screw-in electrical socket of a traffic signal. The LED lamp includes a socket housing, a printed circuit board and a plurality of light emitting diodes. The socket housing has a lower end terminating in a threaded base for insertion into a threaded screw-in electrical socket. The printed circuit board is rotatably mounted to the socket housing. The plurality of light emitting diodes is mounted on the printed circuit in such a manner that they form a symbol image, such as an arrow, a pedestrian walking, a hand, a letter or even words. The printed circuit board is rotatable relative to the socket housing for rotation of the symbol image formed by the light emitting diodes to a desired rotational orientation relative to the socket housing. Therefore, once the threaded base is fully inserted into the threaded screw-in electrical socket of a traffic signal, the printed circuit board can be rotated relative to the socket housing so that the symbol image is properly oriented.
