Compared to other segments in the LED lighting industry, the automotive lighting market is much larger and has higher growth potential. Moreover, its low price sensitivity allows suppliers to realize greater profit growth opportunities. In recent years, driven by the call for energy conservation and carbon reduction, and the four new trends in the automotive industry, the value of automotive lighting has been further explored. Numerous domestic and foreign automotive lighting and automotive LED manufacturers have flocked to this sector. They have collectively contributed to the diversified and high-end automotive lighting market seen today. This phenomenon was vividly demonstrated at the Shanghai Automotive Lighting Exhibition (ALE) held from September 21 to 22, 2023.


After visiting the event, LEDinside identified four major trends throughout the market :

  1. LED auto lamps accounted for the majority of the exhibited products, indicating that LED is capturing more shares in the automotive lighting market.

  2. Adaptive driving beams (ADBs), full-width taillights, Mini LED taillights and vehicle-mount interactive lamps have become the new standard that is revolutionizing the automotive lighting sector. In particular, matrix LED headlights and Micro LED headlights—regarded as advanced ADB technologies—have become increasingly mature.

  3. In response to the rise of self-driving cars, marker lamps installed as part of automated driving systems (ADS) have gradually become popular.

  4. Automotive Mini LED displays garnered a wide range of attention. From lighting to displays, automotive LED makers have expanded their business to various fields.
