Connected to one pole of 2. The other pole of the ignition switch 2 is connected to a movable contact 3a of a lighting switch 3 for switching between day and night and a B terminal of a turn signal relay 4. The lighting switch 3 has a daytime point 3b and a nighttime point 3c, and the movable contact 3a contacts either one to switch between day and night.

A daytime contact 3b of the lighting switch 3 is connected to a fixed contact 5a of the blinker lamp 5. The turn signal switch 5 has two movable contacts 5.
b, 5c are provided, and these movable contacts 5
b, 5c can be moved to the left or right by tilting the knob 5d to the right or left to switch the circuit. The movable contact 5b switches the connection between the fixed contacts 5e and 5f and the fixed contact 5a, and the movable contact 5c switches between the fixed contacts 5g and 5a.
This is for switching the connection with the fixed contacts 5h and 5i.

Reference numerals 6, 7, 8, and 9 are running lamps that also serve as turn signal lamps, and running lamps 6 and 7 are installed on the left side of the vehicle body, and running lamps 8 and 9 are installed on the right side of the vehicle body. be. These running lamps 6, 7, 8, and 9 have large capacity filaments 6a, 7a, 8a, and 9a of 23 watts, and filaments 6b, 7b, and 8 watts of small capacity, respectively.
8b and 9b are connected in series, and the connection point is grounded. The running lamps 6 and 7 are connected in parallel, and the running lamps 8 and 9 are connected in parallel.

filaments 6a of running lamps 6, 7;
One end of 7a is the fixed contact 5 of the turn signal switch 5
e, 5i, and the filaments 6b,
One end of 7b is connected to the nighttime contact point 3c of the lighting switch 3, together with one end of the filaments 8b and 9b of the running lamps 8 and 9. One ends of the filaments 8a and 9a of the running lamps 8 and 9 are connected to the fixed contacts 5f and 9a of the turn signal switch 5, respectively.
Connected to 5h. A fixed contact 5g of the turn signal switch 5 is connected to the L terminal of the turn signal relay 4.

At the nighttime point 3c of the lighting switch 3,
Furthermore, the movable contact 10a of the beam changeover switch 10 and one end of the tail lamp 11 are connected. The fixed contacts 10b and 10c of the beam changeover switch 10 are connected to the two filaments 12 of the headlamp 12.
A, 12b are connected at one end. The connection point between the filaments 12a and 12b and the other end of the tail lamp 11 are grounded.

This circuit connected in this way operates as follows. The illustrated state is when driving straight in the daytime, and in this case, when the ignition switch 2 is closed, the current from the battery 1 is transferred to the ignition switch 2, the movable contact 3a of the lighting switch 3, the daytime contact 3b, and the turn signal. Fixed contact 5a, movable contact 5b, fixed contact 5e, 5 of switch 5
f, and the larger capacity filaments 6a, 7a, 8a, 9 of the running lamps 6, 7, 8, 9
This means that a will always be lit.

In this state, when attempting to make a right turn and tilting the knob 5d of the turn signal switch 5 to the right as shown in Figure 2, the movable contacts 5b and 5c simultaneously move to the left, causing the running lamp attached to the right side of the vehicle to move. Since the current to the filaments 8a, 9a is cut off, the filaments 8a, 9a are turned off. At this time, the filaments 8a and 9a are connected in series to the blinker relay 4 by the movable contact 5c, so the filaments 8a and 9a blink to indicate direction.

When making a left turn, by tilting the knob 5d to the left, the movable contacts 5b and 5c move to the right,
In contrast to a right turn, the filaments 6a and 7a of the running lamps 6 and 7 flash. At night, the movable contact 3a of the lighting switch 3 becomes the night contact 3.
Since it is tilted to the c side, the fixed contact 5a of the turn signal switch 5 is disconnected from the ignition switch 2, and the running lamps 6, 7,
Filaments 8 and 9, 6a, 7a, 8a, and 9a, do not light up.

At this time, the small capacity filament 6 of the running lamp 6, 7, 8, 9 is connected to the movable contact 3a of the lighting switch 3 and the nighttime contact 3c.
Since the filaments 6b, 7b, 8b, and 9b are energized, these filaments 6b, 7b, 8b, and 9b are always lit. When the knob 5d is tilted to the right in order to make a right turn in this state, as shown in FIG. , 9a will blink. The opposite is true for left turns.

The present invention improves the lighting device described above so that, in addition to the above-mentioned effects, it is also possible to reduce battery power consumption. The circuit shown in FIG. 3 is a first embodiment of the present invention, in which the circuit shown in FIG. 1 is adapted for use with an AC power source. To explain this, this circuit uses a sliding type lighting switch 3, and by operating a knob (not shown), two movable contacts 3g,
3j moves upward or downward at the same time and the fixed contact 3
d, fixed contacts 3e and 3f, and fixed contacts 3
It is designed to connect and disconnect between h and 3i.

One end of an AC power source 13, which is a generator driven by an engine (not shown), is connected to the fixed contact 3d, and a fixed contact 5a of the turn signal switch 5 is connected to the fixed contact 3e. The fixed contact 3f also includes running lamps 6, 7,
One end of the filaments 8, 9, 7b, 8b, 9b, one end of the voltage drop resistor 14, one end of the tail lamp 11, and the beam changeover switch 10.
The movable contact 10a is connected to the movable contact 10a. AC power supply 13, voltage drop resistor 14, tail lamp 11
Each other end of is grounded.

The fixed contact 3i is connected to the fixed contact 5k of the blinker switch 5, and the fixed contact 3h is connected to the resistor 15 for load adjustment (because the AC load is halved).
is grounded through. The blinker switch 5 of this circuit is provided with another movable contact 5n that has the same shape as the movable contact 5j and moves simultaneously.By tilting the knob 5d to the right or left, the fixed contact 5o and the fixed contact 5p or fixed contact 5q
It is now possible to switch between. Fixed contact 5
o is connected to the B terminal of the blinker relay 4, the fixed contact 5p is connected to the fixed contacts 5m and 5f, and the fixed contact 5q is connected to the fixed contacts 5l and 5e.

This circuit connected in this way operates as follows. The situation shown is when driving straight during the daytime,
In this case, the current from the AC power supply 13 flows through the fixed contact 3d of the lighting switch 3 and the movable contact 3d.
g, the fixed contact 3e, the fixed contact 5a of the turn signal switch 5, the movable contact 5b, the fixed contacts 5e, 5f, and the filaments 6a, 7a, 8a, 9a of the larger capacity of the running lamps 6, 7, 8, 9. lights up. Since the current from the AC power source 13 flows through the larger capacity filaments 6a, 7a, 8a, and 9a in this way, the power consumption of the battery 1 can be reduced.

In this state, when trying to make a right turn and tilting the knob 5d of the turn signal switch 5 to the right, the movable contact 5
b, 5j, and 5n move to the left at the same time, and the current to the filaments 8a, 9a of the running lamps 8, 9 attached to the right side of the vehicle body is cut off, so that the filaments 8a, 9a are turned off.

At this time, the movable contact 5n moving to the left causes the current from the battery 1 to be transferred to the ignition switch 2, turn signal relay 4, and fixed contact 5.
The light flows through the filaments 8a and 9a of the running lamps 8 and 9 through the filaments 8a and 9a of the running lamps 8 and 9, causing the filaments 8a and 9a to blink. At this time, the fixed contacts 5e, 5l, the movable contact 5j, the fixed contact 5k, the fixed contact 3i of the lighting switch 3,
The filaments 6 of the running lamps 6 and 7 are connected by the movable contact 3j, the fixed contact 3h, and the resistor 15.
The voltage applied to a and 7a is kept constant.

When turning left, the movable contacts 5b, 5j, 5n move to the right by tilting the knob 5d to the left, causing the filaments 6a, 7a of the running lamps 6, 7 to blink, contrary to a right turn. At night, the movable contacts 3g and 3j of the lighting switch 3
is switched as shown in FIG. As a result, the current from the AC power supply 13 flows through the fixed contacts 3d, movable contacts 3g, and fixed contacts 3f of the lighting switch 3, and the filaments 6b, 7b, 8b, and 9b of the running lamps 6, 7, 8, and 9. The filaments 6b, 7b, 8b, and 9b are turned on. At this time, voltage adjustment is performed by the resistor 14.

Incidentally, at night, the filaments 6a, 7a, 8a, 9a of the running lamps 6, 7, 8, 9 are turned on by DC current from the battery 1 only when turning right or left. Therefore, the resistor 15 is unnecessary, so the movable contact 3
separated by j.

The one shown in FIG. 5 is a second embodiment of the present invention, in which only one filament 6a, 7a, 8a, 9a is used in the running lamps 6, 7, 8, 9. It is something. In this circuit, the lighting switch 3 is the one shown in Fig. 3 with two additional fixed contacts 3k and 3l added, and when driving at night, the movable contact 3g is switched to the fixed contact as shown in Fig. 6. 3f and 3l at the same time, and the resistor 14 is connected in parallel to the AC power source 13, so that a lower voltage than when driving at night is applied to the filaments 6a, 7a, 8a, of the running lamps 6, 7, 8, 9. 9a. Note that a resistor 15 is connected between both movable contacts 3h and 3k and the ground to adjust the voltage both during the day and at night.

Since the present invention is configured as described above, it has the advantage that when a two-wheeled vehicle is provided with a running lamp that also serves as a blinker lamp, it can be easily operated. Since the large capacity filament, which consumes a large amount of current when the light is turned on, is supplied with current from the AC power supply, it is possible to reduce the current consumption from the small capacity battery installed in the motorcycle, and reduce battery discharge. It is highly effective in resolving problems caused by
