Compliance overview
Scope and applicability
This standard applies to the installation of lighting and light-signalling devices on motorcycles and mopeds, specifically covering vehicle categories L1 (two-wheel mopeds), L2 (three-wheel mopeds), L3 (two-wheel motorcycles), L4 (motorcycles with sidecars), and L5 (three-wheel motorcycles). It is mandatory for all manufacturers targeting the Chinese market with these vehicle types. It does not apply to M, N, or O category vehicles, which are covered by GB 4785.
Technical requirements
The standard mandates general installation requirements ensuring that devices function reliably under normal vibration. It specifies that paired lamps must be symmetrically installed, share identical photometric characteristics, and illuminate simultaneously. Manufacturers must ensure no red light is visible from the front and no white light is visible from the rear of the vehicle. For specific provisions, the standard details the configuration, geometric visibility, and circuit connections for various lamps such as passing beams, driving beams, front fog lamps, and daytime running lamps. A significant addition is the inclusion of requirements for advanced systems like the Adaptive Driving Beam (ADB) and the Horizontal Inclination Adjustment System (HIAS), which require specific fault indicators and automatic calibration capabilities. The standard also introduces new safety signaling requirements, including provisions for emergency braking signals and rear-end collision warning signals. These systems must activate automatically under defined conditions, such as specific relative velocities and time-to-collision thresholds, utilizing existing turn signal or stop lamps to flash at prescribed frequencies. Manufacturers must adhere strictly to the lamp equipment and color requirements matrix provided in the standard's normative appendices.
Testing methods
Compliance is verified through type approval testing and conformity of production inspections. Key evaluations include visual and photometric tests to confirm the invisibility of front red light and rear white light, ensuring intensity does not exceed 0.25 cd in restricted zones. For advanced features like ADB and automatic driving beam control, the standard mandates real-world road testing under various traffic and road conditions to verify sensor performance and prevent glare to other road users. Additionally, it specifies methods for calculating the vertical inclination of passing beam cut-off lines and the maximum illumination area center tilt for ADB systems.
FAQs
What products and vehicle categories are regulated under GB 18100-2025?
GB 18100-2025 applies to motorcycles and mopeds, specifically covering vehicle categories L1 (two-wheel moped), L2 (three-wheel moped), L3 (two-wheel motorcycle), L4 (motorcycle with sidecar), and L5 (three-wheel motorcycle). It is mandatory for all these vehicle types.
Are there any significant updates from the previous version of GB 18100?
The 2025 revision consolidates the previous three-part series (GB 18100.1/2/3-2010) into a single document. Major updates include the introduction of requirements for Adaptive Driving Beam (ADB), Horizontal Inclination Adjustment System (HIAS), daytime running lights, emergency braking signals, and rear-end collision warning signals.
Can automotive lighting devices compliant with GB 4599 or GB 5920 be used on motorcycles under this standard?
Yes, the standard permits the installation of automotive lighting and light-signalling devices that comply with GB 4599 and GB 5920 (excluding variable-intensity signal lamps and signal lamp projection functions), provided they meet the functional and installation requirements specified in GB 18100-2025. Manufacturers must ensure these devices match the exact functional requirements.
