LIGHTING FOR SAFETY

AN EXPERIMENTAL REAR LIGHT-SIGNAL SYSTEM FOR USE ON CAR OR TRUCKS IS DESCRIBED. THE SYSTEM PROVIDES INFORMATION FOR DRIVERS FOLLOWING VEHICLES; WHETHER THE VEHICLE IS SLOWING DOWN, DECELERATING, CRUISING UNDER STEADY ENGINE POWER, OR ACCELERATING; WHETHER THE VEHICLE IS BRAKING, LIGHTING, MODERATELY, OR HEAVILY; AND WHETHER THE VEHICLE IS IDLING. BASICALLY, THE PRINCIPLE OF OPERATION FOR BOTH CARS AND TRUCKS IS THE SAME. ONE LIGHT SYSTEM INDICATES ENGINE OPERATING CONDITION, AND IS ACTUATED BY A SWITCH SENSING THE ENGINE MANIFOLD VACUUM. THE OTHER LIGHT SYSTEM INDICATES THE INTENSITY OF STOPPING, AND IS ACTUATED BY A SWITCH SENSING THE OUTPUT PRESSURE OF THE BRAKE MASTER CYCLINDER, PLUS THE REGULAR STOP LIGHT SWITCH. /FO/
