Road illumination devices and systems for motor vehicles
1 Scope
This document specifies the same type determination, overall requirements, light source
requirements, light color requirements, photometric performance, photometric stability,
test methods and inspection rules for road illumination devices and systems for motor
vehicles.
This document applies to the design, manufacture and acceptance of road illumination
devices and systems such as passing beam, driving beam, front fog lamps, corner lamps,
etc. used in M and N category vehicles.

5.4 Reference center marking
The device or system shall be marked with the reference centre, and the marking
method shall comply with the provisions of Appendix A. If two driving beam
headlamps are installed on each side of the vehicle, each driving beam headlamp shall
be marked separately.
5.5 Driver assistance projection function requirements
5.5.1 The applicant or manufacturer shall provide a list of driver assistance projection
functions, which shall not cause discomfort, dazzle or distract other road users.
5.5.2 Only the functions listed below are allowed to use the driver assistance projection
function:
-- passing beam (shall comply with the requirements of 8.2.9);
-- driving beam (shall comply with the requirements of 8.3.6).
5.5.3 The light color of the marking or pattern of the auxiliary projection function shall
be white.
5.5.4 The lateral distance from the outer edge of the auxiliary projection function
marking or pattern used on the road to the center of gravity of the vehicle shall not
exceed 1 875 mm. The applicant or manufacturer shall prove it by calculation or by a
method approved by the certification body.
5.5.5 Auxiliary projection function markings or patterns are allowed to flash when
emergency danger signals (such as rear-end collision warning signals, emergency brake
signals, danger warning signals, etc.) are working. In this case, the flashing frequency
shall be 4.0 Hz ± 1.0 Hz.
6 Light source requirements
6.1 Replaceable light source
6.1.1 For replaceable filament light sources, they shall be able to be installed in the
correct position of the luminaire without the use of tools, even in the dark.
6.1.2 The types and performance requirements of replaceable filament light sources,
gas discharge light sources and LED (light-emitting diode) light sources used in devices
or systems shall comply with the provisions of UN R37, UN R99, UN R128 and R.E.5.
6.2 Non-replaceable light source
6.2.1 For light sources that can only be replaced as a whole with the device or
installation unit, filament light sources or gas discharge light sources shall not be used.
This requirement does not apply to corner lights.
6.2.2 Headlamps may use LED modules or laser light source modules. If laser light
source modules are used, the passing beam and driving beam shall comply with the
requirements of 4.4 of IEC 60825-1:2014 and the requirements of BLH-C of IEC
62471-7:2023. Laser modules are not allowed to be used in front fog lamps and corner
lamps.
6.2.3 The LED modules or laser light source modules used in the device or system shall
be able to prevent misoperation and their design shall comply with:
a) Ensure that each LED module or laser light source module can only be installed
in the correct position and can only be removed using tools;
b) If multiple LED modules or laser light source modules are used in the same
lamp body, ensure that modules with different characteristics cannot be
interchanged;
c) LED modules or laser light source modules are not mechanically
interchangeable with other replaceable light sources, even with the use of tools.
7 Light color requirements
The light color of the device and system shall be white, and the light color of the front
fog lamp can also be selectively yellow. The chromaticity characteristics shall comply
with the relevant provisions of GB 4785.
8 Light distribution performance
