ABSTRACT:
A combination trouble lamp and emergency flasher which is adapted to be connected directly to the terminals of a vehicle battery. The device comprises an adaptor cable having a pair of spring biased battery clamps which connect to a female twist-to-lock connector through a pair of heavy gauge insulated cables. The lamp comprises a housing having a socket in which a DC electric light bulb is received, an arcuate reflector made of a highly visible translucent plastic material behind the bulb, and a protective cage hingedly connected to the reflector and positioned in front of the bulb. The lamp includes a relatively long, light gauge power cord which terminates in a male twist-to-lock plug adapted for connection to the receptacle of the adaptor leads. A flasher unit selectively inserted into an external receptacle within the housing causes the bulb to blink on and off and this will appear as a flashing, colored light source when viewed from behind the translucent shade so that the lamp may also serve as an emergency signal light. In another embodiment, the adaptor leads have a dual socket connector so that another pair of battery clamps may be connected thereto for the purpose of jumping a disabled vehicle yet permitting the lamp to remain plugged in.
