Okay, the Alfa Romeo Montreal doesn't have pop-up headlights, but the design is so cool that it deserves recognition. 

During normal driving, the Montreal features louvered panels that cover the top half of the headlights and make the coupe look like it has eyelashes. However, when the time comes to turn on the lights, these pieces tip downward to sit underneath the lamps. The result is a machine that appears to be blinking when the headlights come on.
