中国监管部门已明确禁止L2级辅助驾驶车辆安装智驾小蓝灯，从2026年7月27日起新认证车型将不予通过审核[1]。这一禁令源于蓝色属于公安、消防、救援等特种车辆的专属灯色，而现行国标GB 4785-2019仅允许白、红、琥珀、黄四种外部信号灯光[1]。为确保执行效果，监管体系形成了"新车禁装、存量整改、年检严控"的全链条管控体系[1]，存量车将通过OTA升级、硬件适配等方式关闭行驶状态下的蓝灯点亮功能[1]。
尽管L2级车型面临禁用，但业界普遍认为L3级自动驾驶因涉及人车权责的重大变化，需要外部标志提示其工作状态，L3将成为配备智驾提示灯的标配[1]。国际标准SAE J3134规定使用青绿色光源标识自动驾驶状态[1]。工信部曾在2021年国家标准征求意见稿中规定L3级及以上车辆应配备ADS标志灯，但这一条款在2024年正式发布的国标中被删除[1]。《智能网联汽车自动驾驶系统安全要求》强制性国家标准将在2027年7月1日正式实施[1]，新的标准框架预计将重新定义L3级以上车型的提示灯要求。理想L9曾在2022年率先搭载5颗智驾小蓝灯[1]，成为这一阶段的代表产品。
China's regulatory authorities have prohibited Level 2 assisted driving vehicles from installing the "smart driving blue indicator light" effective July 27, 2026, with new vehicle models failing certification if equipped with the feature [1]. The ban stems from blue being a color reserved exclusively for specialized vehicles such as police cars, fire trucks, and emergency responders, while the current mandatory national standard GB 4785-2019 permits only white, red, amber, and yellow for external signal lights [1].
The regulatory framework now encompasses a comprehensive control system spanning "prohibition on new vehicles, retrofitting of existing fleets, and strict inspection protocols" [1]. Existing vehicles equipped with blue lights will have the illumination function disabled during operation through over-the-air updates and hardware adaptations [1]. However, Level 3 autonomous driving systems are expected to receive different treatment due to their fundamental shift in human-vehicle responsibility allocation, with industry consensus pointing toward Level 3 vehicles becoming the standard bearer for smart driving indicator lights [1]. This aligns with international standards, as the SAE J3134 specification designates cyan-green light sources for marking autonomous driving status [1].
The broader regulatory landscape reflects earlier intentions that were subsequently reversed: the Ministry of Industry and Information Technology's 2021 draft national standard specified that Level 3 and above vehicles should be equipped with automatic driving system indicator lights, but this requirement was removed from the final national standard published in 2024 [1]. A new mandatory national standard on intelligent connected vehicle automatic driving system safety requirements is scheduled for formal implementation on July 1, 2027 [1].
