ABSTRACT:
A safety-promoting device provided in the form of an electrical circuit that reminds vehicle operators to use the turn signals supplied with the vehicle in a safe manner. The circuitry has no effect where the operator properly begins signaling a turn prior to the commencement of a braking operation associated with a turn, but causes the immediate activation of a reminder bell where a braking operation is not accompanied by use of the turn signals. If a preselected amount of time passes while the driver persists in braking in the absence of turn signal activation, the front and rear turn signal lights will begin flashing to warn other drivers that the vehicle is stopping.
