In China, three draft proposals for RID (Road illuminating devices); LSD (light signaling devices), and RRD (retro reflective devices) have been published, and authorities are inviting lighting community to provide feedback by 16 of November 2021. These new texts are based on a copy-paste of UN R148, R149 and R150, with some additional requirements. The main differences are:
• Introduction of road projection and signaling projection on the road
• Introduction of lit logos (with only the possibility as a part of position lamp)
• Introduction of AV signaling lamp, mandatory for L3 vehicles
• Modification of the AFS class for low beam. This will create divergence from the UNECE beam; that is never good news, for it always means additional complexity and cost
• Minimum size for stop lamp: not less than 15 cm2 of apparent lit area in the direction of the reference axis (it will be interesting to see what results this drives, and compare its effect to the 50 cm2 supposedly required by the widely-ignored American EPLLA requirement)
• More performant reversing lamps, inspired by the recent SAE reversing lamp specification upgrade.
The expected implementation date for the new-type lamps is July 2024, and for the new-type vehicles is July 2025
Detailed information is available online, but only in Chinese.
