ABSTRACT:
A temperature responsive signaling device is provided for use at locations where diesel powered trucks congregate. The device includes a light source with at least two colored lights preferably red and green, a control box having at least two indicator lights and a switch for the selection of an operating mode for the signaling device, and temperature responsive means and temperature sensing means. While the control box and temperature responsive means is preferably located inside a building, the temperature responsive means and light source are normally positioned outdoors. A circuit is provided for coupling a power source to the various components of the signaling device such that the light which is activated depends upon the unit's response to a preselected temperature.
