Claims

[Scope of utility model registration request]

an oscillator circuit, a pair of relays, each of which is enabled when the turn switch is turned on in each direction, and both of which are enabled when the hazard switch is turned on; and a pair of relays that are intermittently turned on and energized by the oscillation output of the oscillation circuit. switching means for energizing the enabled relay; a resistor connected in series with the contacts of each relay for converting changes in the current flowing through the turn signal lamps on each side into changes in voltage; A turn hazard comprising: a lamp breakage detection circuit for detecting breakage of a turn signal lamp; and upon detection of the breakage by the detection circuit, the lighting state of the turn signal lamp is changed from when there is no breakage. Lamp drive circuit.
