The automotive industry has embraced LED lighting. LED headlights caused a sensation when Audi put full LED headlights in the A8 in 2008. Since then, the automotive market has been drawn to LEDs for not only forward exterior illumination, but also brake lights and interior lighting including dashboard illumination, instrument clusters, and entertainment system controls.
LEDs have become part of the color scheme of the car interior and a significant part of how each manufacturer brands its cars. LED-based lighting is in many 2012 cars such as BMWs, Infinities, Lexus, Toyotas, Fords, Chevys and even the Rolls Royce. Audi even featured LED headlights in their 2012 Super Bowl commercial about vampires (they died as the headlights caught them around a campfire).
The main drivers for auto manufacturers are power efficiency and the way that LEDs work with a car’s electrical system that helps save fuel. For example, LED headlights are four times as efficient as halogen lamps and require the vehicle’s alternator to replenish less energy, saving fuel. These benefits are good for the environment. According to Audi, cars equipped with LED headlights accounted for a reduction of 25,000 tons of CO2 emissions in the first year of sales.
