Claims (1)

[Scope of Claim for Utility Model Registration] A speed detector 2 having an optical interrupter 6 attached to a speedometer 38 of a vehicle, and a speed detector 2 having an optical interrupter 6 attached to a brake pedal of the vehicle and activated by stepping on the brake pedal. A brake switch 17, an accelerator switch 20 consisting of a pressure detection switch attached to the accelerator pedal of the vehicle and activated when the accelerator pedal is depressed by a predetermined amount, and a small switch attached to the instrument panel of the vehicle. red light bulb 13
a, 13b, 35a, 35b and small green light bulb 23a
, 23b, 27a, 27b and small light bulbs 31a, 31

b, small red light bulbs 13a, 13b and red lamp 14a
, 14b in a blinking state; and small green light bulbs 23a, 23b and green lamp 24a.
, 24b and a green blinking light source circuit B for operating the small green light bulbs 27a, 27b and the green lamp 28a in a blinking state.
, 28b, and the small red light bulbs 35a, 35b and the red lamp 36a.
, 36b, and a red light source circuit E to turn on the far and near lamps 32a, 32b.
a headlight circuit D that operates to turn off; and each set of small light bulbs and lamps 13a, 14a, 13b, 1 corresponding to each circuit A, B, C, D, E.
4b, 23a, 24a, 23b, 24b, 27a
, 28a, 27b, 28b, 31a, 32a, 3

are connected in series, and the optical interrupter 6 includes a light emitting diode 9 and a photosensitive diode 7 that is sensitive to the light of the light emitting diode, and the free end of the speedometer pointer 39 is connected between the diodes 7 and 9. The transistor 5 is turned on and off by inserting and removing the strip 40 provided on the strip 40.
is formed so as to be interposed between both diodes from when the pointer is at a rest position until it reaches a predetermined low speed indicating position, and the red flashing light source circuit A is activated when the optical interrupter 6 of the speed detector 2 is turned off. The green flashing light source circuit B operates only when the indicator moves and turns on the light interrupter 6, while the brake switch 17 is not activated and the accelerator is not activated. - The green light source circuit C operates only when the switch 20 is not activated and emits a flashing green light.
0 is activated and the light interrupter 6 is in the ON state, the red light source circuit E is activated to emit a steady green light, and the red light source circuit E is activated only when the accelerator switch 20 is not activated and the brake switch 1 is activated.
7 is activated and the light interrupter 6 is in the on state, the headlight circuit D emits a red constant light, and the headlight circuit D connects the far or near lamps 32a, 32b with the light interrupter 6 in the off state. A safety indicator for a vehicle, characterized in that it operates so as to turn off at times and turn on only when a light interrupter 6 is in an on state.
