How often do we see CFL, bulbs, tubelights anymore? What we see instead are beautiful little dots of lights. These are called LEDs, or Light Emitting Diodes. The reason that they are used so often nowadays is that they consume much less electricity and produce less heat, thus wasting less energy.
One industry which has witnessed a large rise in the usage of LEDs is the automobile industry. Many premium new cars now use LED headlamps instead of the more traditional halogens or xenons. These are easier on the eyes on other road users, and do not blind them, unlike halogens on high beam. Also they lend a certain aesthetic appeal to the vehicle if implemented properly. The trend was started by Audi, but now has been adopted by many major manufacturers.
