Illumination signal system
Overview
Illumination signal system is an important guaranty for the safe driving of the vehicle. It includes the headlamp illumination
system, signal lamp control system and horn system.
Headlamp illumination system:
We need to use the headlamp to illuminate the road surface and inform the surrounding vehicles or people of its presence
while driving at night; use the high-beam while driving at intermediate or high speed, and use the low-beam while meeting
other vehicles; the low-beam shall be anti-dazzled
Signal lamp control systems:
In a turning drive, the vehicle shall prompt the surrounding vehicles and people to dodge by the flash of the turn lamp;
while driving at night, it shall inform of its presence by the tail lamp
’
s front / rear position lamp, and illuminate the number
on the license plate; while braking, it shall illuminate the brake lamp to inform the vehicle behind of its braking deceleration.
The flash of the turn lamp is controlled by a switch and a flasher, and the illuminations of other lamps are controlled only
by a switch.
Horn system:
When there are other surrounding vehicles or pedestrians are or will likely hinder your driving, use horn to alert them for
safe driving. The operation of the horn is controlled by the horn button.
