This study evaluated the power consumption of traditional and LED-based exterior lighting systems on passenger vehicles, examining nominal consumption as well as realistic consumption based on real-world usage patterns of various lighting equipment obtained in a naturalistic study employing a large, random sam-ple of drivers. The results indicate that an all-LED system using the current generation of LEDs would result in general power savings of about 50% (nighttime) to about 75% (daytime) over a traditional system. The effect on long-term savings for the LED system depends upon the type of vehicle in use (gasoline-powered vs. electric). Long-term distance savings (range) were greater for the electric vehicle. Also presented are calculations of potential savings for two different scenarios of future improvements in LED power consumption, and potential reductions in carbon dioxide emissions.
