Foreword
All content in this Standard is compulsory.
This Standard was drafted in accordance with the rules in GB/T 1.1-2009.
This Standard serves as a replacement of GB 23255-2009 Photometric Characteristics
of Daytime Running Lamps for Motor Vehicles. In comparison with GB 23255-2009,
apart from editorial modifications, the main technical changes are as follows.
---The title of the Standard is modified from Photometric Characteristics of Daytime
Running Lamps for Motor Vehicles in the previous version into Photometric
Characteristics of Daytime Running Lamps for Power Driven Vehicles in this
version;
---Category-L is added to the scope of application of this Standard;
---Requirements towards light source module are added;
---Requirements towards interlocking lamp are added;
---Requirements towards visual surface area are changed;
---Requirements towards the maximum luminous intensity are modified;
---H-H line photometric requirements are modified;
---The range of photometric angle is added.
The amendment of this Standard takes ECE R87 Rev3 Uniform Provisions Concerning
the Approval of Daytime Running Lamps for Power-driven Vehicles by the United
Nations Economic Commission for Europe, including the corresponding amendment
(ECE R87 Rev3 Amendment-1) as a reference.
This Standard was proposed by and shall be under the jurisdiction of Ministry of
Industry and Information Technology of the People’s Republic of China.

normal operating conditions, even if they are under vibration, they could still comply
with the operating requirements and the stipulations in this Standard.
5.2 Light Source Module
5.2.1 Light source module shall be designed to be merely installed on the right position.
Light source modules, other than 5.3.1, shall only be dismantled through tools.
5.3 Replaceable Light Source
5.3.1 Daytime running lamps shall use light sources that comply with the stipulations
in GB/T 15766.1, ECE R37 or ECE R128.
5.4 Visual Surface Area
Visual surface area of the reference axis direction shall be not less than 25 cm2, and
not more than 200 cm2.
5.5 Chromaticity
The light color of daytime running lamps shall be white. Its chromatic characteristics
shall comply with the stipulations in GB 4785.
5.6 Photometric Characteristics
