Abstract
The invention is characterized by a box adapted for mounting on the dashboard of a motor vehicle containing an electrical circuit connected to the vehicle electrical system. The circuit activates sequentially two alarms, first a visual display, then an audio alarm. The alarm is activated by a random timer which is capable of recycling when a deactivating bar is depressed. A series of five time intervals are capable of determining the time interval between recycling periods of the random timer.

A driver attention alarm comprising:
- an enclosure having four walls and a top and bottom;
- an electrical circuit positioned within the enclosure;
- a source of electrical power applied to the electrical circuit;
- a means for controlling the power into the circuit;
- a first alarm means activated by the electrical circuit to attract a drivers attention;
- a random timer circuit connected to the source of electrical power for activating the first alarm means;
- an adjustable timer circuit connected between the source of electrical power and the random timer circuit for selectively controlling the time between activation of the random timer circuit;
- a second alarm means connected to the random cycle timer to attract a drivers attention after a preset period of time, and
- a means for recycling the random timer circuit after the first alarm is activated, whereby the random timer will deactivate the alarms and renew its cycle.
