Traffic lights using state-of-the-art LED illumination use 90 percent less electricity, offer a much longer service life and are more durable than their incandescent counterparts. Taking advantage of the countless benefits, cities around the country have been replacing traditional filament-based traffic signal bulbs with LEDs for years. Unfortunately, the low-watt LED units burn much cooler than its white-hot counterpart making it unable to melt snow off weather exposed traffic fixtures.
Back last spring, Audi began offering an optional all-LED headlamp cluster on its R8 sports car as a $5,600 option. The new R8 V10 that was announced in early December will incorporate these LED lamp clusters as standard equipment. The R8 V10 is the first car in the world to get LEDs for both the high and low beams. The LEDs use only one quarter of the energy of conventional halogen lamps and Audi expects that energy consumption to drop by another half over the next decade. That amounts to signi
In the ongoing effort to improve fuel efficiency on vehicles, automakers are looking for ways to reduce parasitic losses that absorb power from the engine rather than sending it to the drive wheels. That means replacing constant drive hydraulic steering assist systems with on-demand electric equivalents and just generally trying to cut the power requirements for all accessory systems. One area that draws power is the lighting system. Cutting the power requirements for headlights is a tricky prob
