On Oct. 20 the Ministry of Industry and Information Technology’s Equipment
Industry Division I published a draft Installation Requirements for External
Lighting and Optical Signal Devices of Motor Vehicles and Trailers (for
comment). It bars vehicles without Level‑3 or higher automated driving systems
from installing ADS indicator lights. The draft mandates ADS lights use a
blue‑green color (previous L2 assist lights were commonly blue). When a Level‑3
or higher automated driving function is activated, all ADS lights must
automatically illuminate and remain lit while the system is active; ADS lights
are prohibited from illuminating at Level‑2 or below and must automatically
extinguish when the automated driving system disengages. Manual on/off control
of ADS lights is prohibited.
