LEDs Light Up Detroit Auto Show

Many of today's vehicles use LED-based center high-mount stop lamps, headlights, and taillights. But the LED penetration has gone beyond such basics. The new Acura TLX prototype, for example, has a row of LED lights on its mirrors. Cadillac places LEDs on the rear decklid of its CTS sedan. Ford has even put them on the door sill plate of its Mustang. And many other manufacturers use LEDs for daytime running lamps, fog lamps, and for eyebrows above the headlights.
