ABSTRACT:
A light emitting diode array mounted on a printed circuit board is provided with capacitive means to reduce voltage, mounted in a glass tube and provided with a standard candelabra or other base for insertion into a light socket in a slim line exit or other sign. In a preferred embodiment the circuit board is rotatable relative to the metal base so as to facilitate maximum light emission from the sign.
