ABSTRACT:
A protection system has a power supply connected to lamps by a low value resistor. The resistor is part of a voltage divider system which provides input signals to a number of comparators. These comparators provide appropriate signals to a microprocessor to indicate normal operation. When a malfunction is detected, the voltage drop across the low value resistor changes and alters the output of the comparators. The microprocessor thereafter produces an appropriate warning signal. In a vehicle turn signal circuit, the present invention is incorporated to detect a burned out bulb. A warning is provided to the vehicle operator when a bulb is out. Further, pursuant to federal safety regulations, the remaining functioning bulbs, when activated, flash at a substantially slower rate.
