A bright road ahead

摘要

Automotive lighting has evolved continuously since the invention of the motorcar. The flames of the old acetylene lamps have long been extinguished with the arrival of the electric headlamp, which can be seen in the form of halogen and HID (high intensity discharge) lamps on the majority of today's vehicles. The past 15 years, however, has seen two new illumination technologies begin to light up roads with increased brightness and energy efficiency: LEDs and lasers. The latter was introduced to commercial vehicles in 2014.
