Abstract

PURPOSE: To annunciate the high speed of a car by changing the flashing repetition frequency of a direction indicator when the driving speed of the car is dangerous to curb operation.
CONSTITUTION: Power is applied to the control circuit 3 from the battery 1 loaded on a car through the key switch 2 and current supply signals are intermittently applied to the direction indicating flashers 4a and 4b through this control circuit 3. The car speed detection circuit 26 measures the intermittence frequency of the detection switch 27 which is intermittent at the frequency in proportion to the car speed. When the frequency exceeds the preset one, the circuit 26 outputs the signal of "1". This output changes the repetition frequency of the flashers 4a and 4b.
