• a first circuit sensing power applied to set first set of lights when said turn signals have been activated, said first circuit providing a first signal indicating that said turn signals have been activated;
• a second circuit sensing the power applied to said first set of lights, said second circuit providing a second signal only when said first set of lights are energized indicating that said brake pedal has been depressed and when said emergency blinkers have been activated in a vehicle that utilizes said first set of lights for turn signals, brake lights and emergency blinkers;
• a third circuit sensing the power applied to said second set of lights, said third circuit providing a third signal only when said second set of lights are energized indicating that said brake pedal has been depressed in a vehicle that utilizes said second set of lights for brake lights;
• a timing circuit that is energized responsive to said first signal to time a predetermined period;
• either said second signal or said third signal preventing said timing circuit from being responsive to said first signal to time said predetermined period;
• and
• an alarm responsive to said timing circuit having timed said predetermined period to provide a fourth signal to an operator of said vehicle that the turn signals are activated.
