Let There be Light: LEDs to Trickle Down to More Mainstream Models
It wasn’t too long ago when LED (light-emitting diodes) lights were a feature one could only find in the top end premium cars. Today, they have become cheap enough to be produced in large quantities and as a result, are storming the car market.
LEDs are much more energy-efficient than conventional halogen bulbs because they do not generate light from heat. For example, a Visteon-designed LED headlight for a Bentley requires only 15 watts for the low beam, whereas an equivalent halogen bulb needs 65 watts to do the same job. They last longer as well; about 10,000 hours or 10 times longer than a halogen unit.
