It's time to say goodbye to the L2 small blue light | A quick decision by Lin

原文:是时候告别L2小蓝灯了丨琳机一动

Summary of Key Points

Recent regulatory requirements prohibit new L2-level assisted driving vehicles from using the small blue light indicator, but there are no clear guidelines for already sold or in-production vehicles. This does not mean the complete disappearance of the small blue light; rather, it marks a shift in the industry's approach from initial reliance on symbolic indicators to a more refined governance system that emphasizes substantive responsibilities and rules. The small blue light played a role in helping the public understand the assisted driving status during the early stages of autonomous technology adoption. However, as regulations have matured and awareness has increased, its significance has diminished. In the future, L3/L4-level autonomous driving (where the system takes control of driving) will still require similar external indicators to reflect the regulatory approach of "graded management and retention based on necessity," indicating that the autonomous industry is entering a phase of high-quality, compliant, and safe development.

Why the Small Blue Light Needs to Phase Out Now?

There are three main reasons for this change:

1. Matured awareness and regulations: L2-level assisted driving is still about "a person driving with machine assistance" (e.g., automatic following and lane maintenance). People are becoming more familiar with this functionality, and without the small blue light, they can tell it is assisting them. Additionally, industry standards and regulatory frameworks have become more comprehensive, clarifying responsibilities in the event of an accident, thus reducing the value of the small blue light as a warning mechanism.

2. Adherence to international practices: European regulations stipulate that only L3-level and higher autonomous vehicles are allowed to use external indicators, while L2-level and lower systems are not. Our adjustment follows this logic to avoid overstepping boundaries.

3. Prevention of liability disputes: If L2 vehicles continue to display the small blue light, it might lead others to mistakenly assume the vehicle is driving on its own. In the event of an accident, this could blur the line of responsibility. Banning the small blue light serves to clearly communicate that the driver remains in control and should not rely on the machine.

Why the Small Blue Light Became Popular in the New Energy Vehicle Sector?

In 2022, the Li Auto L9 was the first to feature the small blue light indicator, followed by Xpeng, NIO, and BYD. Its role was crucial at that time:

  • Clarifying confusion: When autonomous technology was new, the small blue light helped pedestrians and other drivers recognize the vehicle's assisted driving status, reducing the risk of misunderstandings (e.g., sudden lane changes).
  • Building a safety foundation: As autonomous technology was still being developed and road conditions were complex, the small blue light served as a signal to others, indicating that the vehicle was using assisted systems and thus requiring extra caution, which contributed to its faster adoption.

The Upgrade in Regulatory Thinking Behind the Ban

This change is not a blanket prohibition but represents a shift from symbolic indicators to clear responsibilities:

  • Moving away from symbols: Safety is no longer solely demonstrated by external signs; instead, it relies on well-defined rules and responsibilities. Whether there is a small blue light or not, drivers must remain attentive to the road.
  • Focusing on safety: The principle of "human control with machine assistance" is firmly established, preventing disputes about who is responsible in an accident. For example, the ban eliminates the excuse that "the system was active, so it's not my fault."
  • Precise governance: The change only applies to newly certified vehicles; existing models are given a grace period, reflecting the flexibility of regulatory measures.

The Small Blue Light Has Not Completely Disappeared and Will Still Be Used in L3/L4 Vehicles

The small blue light is just phasing out temporarily, not permanently:

  • L3/L4 levels require it: For these higher levels of automation (where the system takes over driving, such on highways), it is essential to clearly indicate that the vehicle is autonomous. The small blue light or other compliant indicators will continue to play a vital role.
  • Supporting new regulations: In June this year, China's first mandatory national standard for L3/L4 autonomous driving was approved, requiring clear indicators. In the future, the appearance of the small blue light may change, but its function (indicating autonomous status) will remain.
  • Alignment with international standards: This move aligns with European regulations and makes it easier for Chinese automakers to enter international markets without having to modify their vehicles.

The Rise and Fall of the Small Blue Light Reflects the Growth of the Autonomous Industry

The emergence and disappearance of the small blue light reflect the evolution of the autonomous industry from a period of rapid, unregulated growth to one characterized by maturity and standardization:

  • Initial phase: Innovative measures (like the small blue light) were used to facilitate the adoption of assisted driving.
  • Current phase: Safety and regulation are now the primary drivers, shifting the focus away from flashy symbols to the fundamental responsibilities of drivers, vehicles, and roads.
  • Future phase: With the widespread adoption of L3/L4 levels, precise indicators and regulations will balance technological development with road safety.

This transition indicates that China's autonomous industry has entered a stage of high-quality development, focusing on compliance, safety, and user trust. The ban on the small blue light is not a negative development but a sign of the industry's maturity. It marks a shift from relying on external indicators to internal rules, clarifying responsibilities and avoiding misunderstandings. When L3/L4 levels become commonplace, the small blue light (or its upgraded version) will likely reappear, with a clearer role in indicating that the vehicle is truly autonomous.

In summary, the phasing out of the small blue light is a positive development for the autonomous industry, reflecting its maturation and commitment to better practices. It signifies a shift from a focus on technology to a balance of technology, safety, and user trust, laying the foundation for international expansion.
