This aims to achieve the above-mentioned purpose.

[Operation] The high-mounted stop lamp is provided separately from the stop lamp of the vehicle, and is turned on when a stop lamp switch that turns on the stop lamp is turned on.

On the other hand, when the vehicle's ignition switch is on, the vehicle's tail lamp switch is on, and the vehicle speed signal is O, and a predetermined period of time has elapsed since the stop lamp switch was turned on, Since the high-mounted stop lamp is controlled to dim or turn off, it is possible to prevent light pollution from causing a feeling of dazzle to the driver of a following vehicle.

〔Example〕

FIG. 1 shows an embodiment of the present invention. Here, the same parts as in FIG. 3 are designated by the same numbers.

In this Figure 1, 28, 2°, 23 are main fuses, 30, 3□, 33 are circuit fuses,
7 is the ignition switch, 8 is the tail lamp switch, 94 and 9□ are the tail lamps, 10 is the controller that controls the lighting of the high-mounted stop lamp, 11 is the reed switch, and 12 is synchronized with the axle, for example. This is a vehicle speed detection rotor that rotates at the same speed.

Further, FIG. 2 is a time chart showing signals of various parts in the embodiment shown in FIG. 1, and is for explaining the operation of the high mounted stop lamp control device of the present invention.

The present invention provides a high-mounted stop lamp that controls the lighting of a high-mounted stop lamp 6 that is provided separately from a stop lamp of a vehicle and is configured to be turned on when a stop lamp switch 40 that turns on the stop lamp is turned on. In the control device, there is an input indicating that the ignition switch 7 of the vehicle is on, and an input indicating that the tail lamp switch 8 of the vehicle is on, and the vehicle speed signal based on the vehicle speed detection means 11.12 is In this state, when a predetermined period of time has elapsed since the stop lamp switch 4 was turned on, a controller 10 is provided which controls the high mounted stop lamp 6 to dim or turn off.

Further, to explain this in detail, in the mounted stop lamp system of the present invention, a controller 10 is provided between the stop lamp switch 4 and the high mounted stop lamp 6, The lighting control of the high mounted stop lamp 6 is performed.

This controller 10 has an ignition switch on input that indicates that the ignition switch 7 is on, a tail lamp switch on input that indicates that the tail lamp switch 8 is on, a stop lamp switch on input that indicates that the stop lamp switch 4 is on, and a reed switch. The reed switch signal indicating the on/off state of 11 is input, and necessary arithmetic processing is performed to generate a lighting output for the high mounted stop lamp.

In this case, the tail lamp switch-on input is used as a signal to indicate night time. The reed switch signal is generated depending on the rotation of the vehicle speed detection rotor 12 connected to the axle or the like.
It is generated when the reed switch 11 detects the N pole and S pole of the magnet provided on the rotor 12 and turns them on and off.

The controller 10 generates a vehicle speed signal by performing calculation processing to convert the number of on/off times of the reed switch signal per unit time into vehicle speed.
