1. Lighting and Signal Devices
A. Headlamp and sidelight
The headlamp illuminates the driver's front road so that it is easy to identify various road conditions
and the traffic on the road, and can send signals to persons and vehicles, or expresses an overtaking
intention by flashing the headlamp. When driving in fog, the headlamp is often open to ensure traffic
safety.
The sidelight is used to indicate the position of the vehicle, which meets other vehicles or drives in
the city where the lighting conditions are better at night, or to remind others. It is usually installed in the
headlamp assembly.
The headlamp mainly includes a condenser, glass cover, bulb, lamp holder, lamp cover and shell.
The role of the condenser is to make the light emitted by the bulb be effectively concentrated to form a
beam with high brightness. It is mostly made of stamped aluminum.
The glass cover is mainly used to diffuse the light beam reflected by the condenser, to ensure that a
large enough area in front can be uniformly lighted, to avoid making an oncoming driver dazzled.
Bulbs can be divided into mono-filament bulbs and double-filament bulbs.
A lamp holder is generally stamped from galvanized sheet iron and has a cylindrical shape with three
unequal lugs at the edge and a hole opened at the bottom, through which wires can pass.
The lamp cover and the shell form a complete space, accommodating the rest of the headlamp.
B. Tail lamp and brake lamp
Tail lamps are used to show the position of vehicles rearward and make the license number clearly
visible at night. A tail lamp mainly includes the lampshade, lamp shell, lamp holder and bulb. The
lampshade is made of red plexiglass and the lower part is fitted with a transparent plexiglass window so
that the light can illuminate the license plate.
The lamp shell is made of plastics. Each side of the bottom is a support with a round hole. The lamp
can be connected with the lamp shell by screws.
C. Klaxon
In the process of driving, a motorcycle driver can make the klaxon to sound through the switch, to
remind pedestrians and other vehicles and ensure traffic safety.
According to different power supplies, klaxons can be divided into AC klaxons and DC klaxons. This
model adopts a DC klaxon.
D. Sidelight
When the motorcycle intends to turn a corner, the sidelight can emit yellow light flashing signal
through the flicker relay to remind others that the vehicle is to make a turn. A sidelight generally includes
lamp shell, lamp holder, light bulb and lampshade.
