PURPOSE: An emergency lamp and turn signal light control device for a vehicle is provided to prevent accidents by indicating the processing direction of the preceding vehicle to the following vehicle with blinking the turn signal light fast in turning on the emergency lamp. CONSTITUTION: An emergency lamp and turn signal light control device is composed of pull-up resistances(R1-R3) connected to an emergency lamp switch(1) and a turn signal light switch(2) to apply power; a first signal processing unit(3) connected to the turn signal light switch to output by reversing the signal level; a timer circuit(16) outputting frequency and a control signal by counting the oscillating frequency, and generating power for setting blinking cycles of first and second lamps(7,8) according to operation of the turn signal light switch; a second signal processing unit(4) outputting a control signal by combining the output of the first signal processing unit and the output of the timer circuit; a drive(5) turning on first and second lamps by combining output signals of the second signal processing unit and the emergency lamp switch; and a switching unit(6) supplying power to first and second lamps according to the output signal of the drive. The direction of the preceding vehicle is indicated to the following vehicle with blinking the turn signal light fast in turning on the emergency lamp. The turn signal light is turned off after set time with turning on the emergency lamp.
