ABSTRACT:
An all-purpose lamp for use with vehicles. The lamp includes an air impervious housing having a lens formed therein in optical alignment with a bulb carried within the housing. The housing is open at its lower end for receiving a bulb carrier which is movable relative to the housing. Movement of the bulb carrier controls the on-off operation of the lamp. In one embodiment this switching function is effected by operation of a slide supported on the lamp housing and engaging the bulb carrier. Movement of the slide relative to the lamp housing will effect a corresponding movement of the bulb carriage, thereby moving the bulb in to and out from engagement with a pair of electrical contacts supported within the upper portion of the lamp housing. In this manner, illumination of the lamp is controlled by moving the slide to effect a corresponding movement of the bulb carrier into engagement with the electrical contacts coupled to the vehicle power supply. Movement of the slide in the opposite direction and, therefore, the bulb carrier relative to the lamp housing, will physically separate the bulb from the energizing contacts thereby terminating illumination.
