LEDs have been the light source of choice for automotive interior lighting for years, particularly for signal applications. Owing to recent advances in solid-state lighting, LEDs are now being designed for exterior applications as well. Although primarily used in center high-mount stop lamps and rear combination lamps, LEDs continue to gain ground for most of the automotive interior and exterior lights.

Solid-state light sources are being widely adopted owing to their attributes such as small size, robustness, long lifetime, and high efficiency. Automotive manufacturers are attracted by the potential reduction in energy consumption and the space savings realized by smaller lighting fixtures. The styling potential of LEDs brings advantages for consumers, because it enables more attractive and distinctive designs.
