With the launch of ADB (Adaptive Driving Beam) smart headlights by Daimler Group in 2017, a new wave of innovation has swept through the automotive electronics industry. Recently, Danyang Yishan Auto Lamp Equipment Manufacturing Co., Ltd., a subsidiary of Hongli Zhihui, successfully secured a bid for an ADB development project with a major domestic automaker. This milestone marks a significant step forward in the intelligent transformation of Hongli Zhihui's LED lighting solutions.
As a key subsidiary of Hongli Zhihui Holdings, Yishan Auto Lamp is a private company with over two decades of experience in manufacturing automotive lamps. The company specializes in the independent research and development, prototyping, production, and sales of auto lamps. Its product range includes complete vehicle lighting systems such as front and rear combination lamps, interior lights, and more. Yishan Auto Lamp is capable of developing lighting systems in sync with main engine factories, giving it a strong industrial advantage in the market.
**ADB Solves Nighttime Driving Safety Issues**
According to data from traffic authorities, the risk of traffic accidents at night is 1.5 times higher than during the day, with 55% of all accidents occurring after dark. This is largely due to poor visibility, inadequate lighting habits, and changes in drivers' visual performance at night, which can lead to unsafe driving behaviors. Improving nighttime driving safety is therefore crucial.
To address this challenge, many automakers and suppliers are turning to advanced technologies like ADB. ADB, or Adaptive Driving Beam, is a smart headlight system that uses onboard cameras to detect other vehicles and automatically adjusts the light distribution. This prevents glare from affecting oncoming drivers while maximizing the driver’s field of vision.
Yishan Auto Lamp has been focusing on delivering safe and comfortable driving experiences. The company began developing ADB technology several years ago and has already achieved promising results. Their recent collaboration with a major car manufacturer highlights the recognition of their independently developed ADB smart headlights. These headlights offer full automatic control, eliminating the problem of glare from other vehicles and improving visibility for the driver.

The growing partnership between Yishan Auto Lamp and leading automotive companies reflects rising market demand. Although ADB technology is currently more common in high-end vehicles, its adoption is expected to expand as LED lighting becomes increasingly intelligent.
Hongli Zhihui emphasized that acquiring a 56% stake in Yishan Auto Lamp allows the company to better leverage its strengths in the LED industry chain. This strategic move aims to accelerate Hongli Zhihui’s expansion into the passenger car LED lighting sector and strengthen its position in the domestic LED lighting supply market. Ultimately, this will enhance the company’s overall competitiveness and support long-term, sustainable growth.
**What is ADB?**
ADB, or Adaptive Driving Beam, is an intelligent high beam system designed to improve nighttime visibility. Using video camera input, the system detects the position and distance of oncoming vehicles and dynamically adjusts the light pattern. It dims or turns off the light in the direction of the oncoming vehicle to prevent glare, ensuring optimal visibility for the driver. As a result, ADB is becoming a key technology in the future of automotive safety lighting.
