1. A display device comprising:
- a first actuation means that corresponds to the state of brake lights on an automobile, said first actuation means having an input for receiving electrical energy and an output for outputting a signal indicative of the state of the brake lights;
a second actuation means having an input for receiving electrical energy and an output for outputting a signal indicative of an emergency condition;
logic circuitry having two inputs for receiving outputs from both the first and second actuation means and providing an output;
a first illumination means coupled to the output of said first actuation means; and
, a second illumination means coupled to the output of the logic circuitry.

Abstract
The invention is a system including a third brake light for an automobile. The brake light is equipped with means for displaying a warning message when an emergency condition arises. Light emitting diodes, thin film transistors, liquid crystal displays, light bulbs or other light emitting or refracting means display a warning message when activated. The light emitting or refracting means operate in a normal mode when an emergency condition is not present.
