LED LIGHTS: A BRIGHT IDEA THAT IMPROVES YOUR FUEL ECONOMY

摘要

IT'S AN OFTEN overlooked fact that the headlights you turn on at night to read the road ahead are directly linked to what comes out of the tailpipe or the range of an EV. Why? If all the lighting on a car, including indicators, is by LED, the power consumption saving compared with using old-school halogen is 60%, and cutting that reduces fuel consumption and emissions. The colour temperature (measured in kelvin and literally the colour of the light) is much whiter than a halogen bulb, which is yellow by comparison, giving superior forward vision. Audi quotes 5500 kelvin for its LED headlights, which, it says, is close to daylight.
