China Automotive Lighting and Ambient Lighting System Research Report, 2025
Automotive Lighting System Research: In 2025H1, Autonomous Driving System (ADS) Marker Lamps Saw an 11-Fold Year-on-Year Growth and the Installation Rate of Automotive LED Lighting Approached 90%.
ResearchInChina released the China Automotive Lighting and Ambient Lighting System Research Report, 2025. Starting from multiple dimensions such as mainstream automotive lighting technologies, automotive lighting chip solutions, and domestic and foreign automotive lighting regulations, this report systematically combs through the technical and regulatory overview of automotive lighting systems; made in-depth analysis of China's automotive lighting market data, covering key indicators like the installations and penetration rate of various types of headlights, and the market performance of leading OEMs, and forecasts the automotive lighting market size from 2025 to 2030; comprehensively analyzes global automotive lighting suppliers, including information on their product matrices and supporting vehicle models, and sorts out lighting application cases of typical vehicle models; finally, conducts an in-depth study and judgment on the development trends of automotive lighting.
1. China's Automotive LED Lighting Market Will Be Worth RMB 80 Billion in 2030.
The installations of LED high and low beams lights continue to grow, with an installation rate of about 90% in 2025H1.
Data on automotive high and low beam lights in China from 2023 to H1 2025 shows that the installations of LED lighting have increased year by year, and its application becomes more widespread, with rising market demand.
In 2025H1, LED low beam lights were installed in 9.412 million vehicles, with an installation rate of 89.1%, up by 9.9% on a like-on-like basis; LED high beam lights were installed in 9.407 million vehicles, with an installation rate of 89.1%, 10.0% higher than the same period of the previous year.
In 2030, the LED lighting market will be valued at more than RMB 80 billion.
According to China's automobile sales volume, China's automotive lighting market will be valued at about RMB65.12 billion in 2025, a figure projected to reach RMB88.22 billion in 2030. China's automotive LED lighting market will be worth around RMB61.87 billion in 2025, a figure projected to increase to RMB82.79 billion in 2030.
2. ADAS Indicator Lights Enjoyed a Year-on-Year Upsurge of 1098% in H1 2025, and Multiple Automakers Made Efforts on Layout.
ADAS indicator light, officially known as the autonomous driving system (ADS) marker lamp (also referred to as the ADS lamp or "little blue light"), is a new intelligent driving marker designed according to regulations and technical standards. It lights up in turquoise color, which can be effectively distinguished from other traditional traffic lights and automotive light colors, and needs to be lit around the clock. In terms of installation in vehicles in recent years, in H1 2025 ADAS indicator lights were installed in 755,000 vehicles, with an installation rate of 7.1%, a year-on-year jump of 1098%.
Seen from the actual installation, ever more automakers are deploying ADAS indicator lights ("small blue lights"). In H1 2025, BYD's installation rate of small blue lights soared to 65.4%, and many of its models such as Qin L, Song PLUS NEV, Seal 06 DM-i, Sea Lion 05 EV, and Dolphin were equipped with small blue lights. In addition, emerging brands such as Li Auto, XPeng, AITO, and Fangchengbao also occupy an important position in this field and have become core application players of small blue lights.
There are two installation modes of small blue lights in vehicle models of automakers, as follows:
1）"OTA Update": For some models, automakers can equip them with the small blue light function via OTA updates. For example, on June 17, 2025, Harmony Intelligent Mobility Alliance (HIMA) pushed an OTA update to AITO M9/M8, adding the small blue light function. When the vehicle turns on the ADAS mode, the blue indicator lights at the front, rear, and exterior rearview mirrors of the vehicle will stay on continuously.
2）"Hardware OTA Update": Some automakers launch hardware OTA upgrade plans, allowing owners of old models to also use small blue lights. For example, in March 2025, XPeng announced the "AI Intelligent Driving Small Blue Light Hardware OTA Crowdfunding Upgrade Plan", which covers a number of XPeng models such as P7, P7i, G6, G9, and X9, with a crowdfunding price of RMB899.
3. Ambient Lighting Develops Beyond the Decoration-only Category and Enables Linkage with Functions Such as DMS/ADAS.
Automotive ambient lighting has broken through its traditional positioning. From a single ambient decoration function, it has evolved into a combination of auxiliary lighting and scenario-based interactive functions, becoming a new intelligent cockpit element to enhance driving and riding experience. From the perspective of application scenarios, the coverage of ambient lighting keeps expanding, and has now extended to multiple areas of the vehicle, such as roof, chassis, front/rear trunk, door handles, and wheels. In terms of functions, its interactivity has been significantly enhanced.
Specifically, ambient lighting can be deeply linked with the IVI system, changing dynamically with music, movies, or game content to create an immersive audio-visual experience. It can also be connected to in-cabin monitoring systems (DMS/OMS) to intelligently identify the emotional state of drivers and passengers and realize emotional interaction through light and shadow changes. In addition, ambient lighting can also be linked in real-time with the vehicle navigation system and ADAS. For example, it can guide the driver's sight through light changes when the navigation prompts a turn, or automatically switch to the "small blue light" color when the ADAS mode is activated to enhance driving safety.
Case (1): The ambient lighting of the Mercedes-Benz S-Class sedan is combined with ADAS. It can provide a red ambient light prompt when turning or detecting a danger.
Case (2): When Li Auto i8 activates AD (Autonomous Driving), the ambient lighting of the audio at the driver's seat will be adjusted to the color of the "small blue light", helping the passengers in the car to well know the status quo of ADAS and improving safety.
