Title: Vehicle lighting monitoring system - uses bulb failure voltage difference to activate warning circuit
Inventor: KAMIN ULRICH
IPC: B60Q11/00
Filed: 1977-04-05
Abstract: The head lamp dipper, the side light, tail light and brake light circuits have separate test circuits. Each test circuit is connected to the emitter of a transistor whose collector is in contact with the vehicle battery via a fuse. The four transistors have a common switch, their bases being connected via resistances whose values correspond to the respective lamp filaments to the contacts of a time switch. The lamp voltage drop is passed by individual trim potentiometers to an OR-gate input and adjusted to give a tension below the normal value of that when the lamps are functioning correctly, and above when one or more filaments fails.
