Until Pixar came along and ruined things, headlights were often seen as a vehicle's eyes. But Mercedes-Benz refuses to give up on that anthropomorphic fantasy. Even to the point of designing a mechanical turn signal system in its new Concept Style Coupe that looks like fluttering, flirting eyelashes.
Instead of simply animating a row of LEDs to indicate that the vehicle was turning right or left, the Mercedes-Benz engineers went a little overboard with a series of metal plates that raise and lower in sequence, revealing a yellow light underneath. The effect is not unlike impatiently drumming your fingers on a table, but it furthers the illusion that the vehicle is defiantly staring you down... or just trying to get your phone number. [Notcot]
