LIGHTINGHEADLIGHT
The parallel-link pop-up headlights are employed
that move up or down vertically as they are turned
ON or OFF. They are aerodynamic to offer less
resistance to air when the vehicle is in forward
motion.
The headlights can be moved up and down with the
lighting switch or pop-up switch. An independent
headlight moving mechanism is provided for theRo3liAAAright and left headlights: should one mechanism fail,
the other remains operative.
In addition, when the passing light is used, the
headlights are turned ON in the lowered position
without popping up.
There is also a manual knob installed that can be
used to move up and down the headlights manually
when maintenance is required.

Pop-upThe mechanism consists of the pop-up motor which moves the
headlights up and down. The hinge and link assembly connect
the pop-up motor to the headlight. When the pop-up switch or
lighting switch is turned ON, the pop-up motor is started
causing the link assembly to move the hinge, which results in
the headlight moving up. A parallel link system is employed for
the hinge, in which the hinge is moved about the two fixed
points as shown, which ensures that the headlights are moved
up and down vertically.

HEADLIGHT RAISING OPERATION
1. Pop-up switch ON, lighting switch OFF
When the pop-up switch is turned ON, current from
fusible link @ flows through the up timer circuit of
the passing control relay, turning ON transistor Trl .
Current from Trl passes through the
U contact of
the U/D (Up/Down) switch of the pop-up motor. This
means that current flows through the pop-up motor
relay, thus energizing the pop-up motor relay.
The energized pop-up
*motor relay means that
current from fusible link @flows through the pop-up
motor, which results in the headlights starting going
up. When the crank arm of the pop-up motor rotatesabout 180” to the UP stop position, the contact of
the interlocking U/D switch changes from
U to D,which cuts off current to the pop-up motor relay. As
a result, the pop-up motor relay is de-energized and
no current flows from fusible link @ to the motor.
This results in the headlights staying in the fully-
raised position.
UP
& DOWN TIMER CIRCUIT
Even if Up/Down operation of the pop-up headlight
becomes abnormal, the Up or Down timer (ON for
5
f 2 seconds) cuts the power supply to the POP-UPmotor to protect the motor.
