Yole's analysts see this growth driven by natural LED cost erosion, the standardization of LED modules and their optimization driving the costs down and accelerating LED adoption in more vehicles.
Since the first full LED headlamp was introduced in 2007, LED technology has gradually penetrated headlamp design. LED technology has allowed lighting to become a distinctive feature and enabled innovative functions like the glare free adaptive high beam introduced in 2013.
Yole's Automotive Lighting: Technology, Industry and Market Trends 2017 report presents all automotive lighting applications and associated market revenue between 2013 and 2022, detailing the integration status of different lighting technologies and systems, technical trends, market evolution and market size by application.
LED technology use had been limited to high-end vehicles and has had to compete with traditional light sources, namely halogen and high-intensity discharge (HID/Xenon). Improved LED performance, lower power consumption and flexible design were the first enablers. Then, cost reductions helped LED technology spread to all vehicle categories.
Automotive lighting is driven by exterior lighting and especially headlamps, generating more than two-thirds of the total market revenue. Rear lighting is the second largest area, representing 17% of total market revenue. Interior lighting represents almost 10% of revenue but growth is expected to be linked to the development of autonomous vehicles and the creation of vehicles as «living homes». Other types of lighting, such as fog lamps, CHMSL or small lamps, comprised the remaining 7% of revenue in 2016.
