Only safety regulations were strong enough to take down this age-old design cue.

Some automotive design trends come and go, while others last for generations. The use of hidden headlights is perhaps the best example of the latter as retractable lights first showed up on the 1936 Cord 810, and they were last used on the 2005 Chevrolet Corvette. Speaking of the Corvette, this car used hidden headlights from 1963 until 2005 with each generation featuring a different take on retractable covers – the C4 had one of the best light design with retractable covers that would do a back flip and rotate a full 180 degrees.

Whether they were created for aerodynamics or style (or a mix of the two), these lights were killed off due to safety, and isn't hard to see why. For starters, a faulty motor or vacuum pump meant that the headlights would not illuminate the road, but they also got phased out to help improve pedestrian safety. Hidden headlights were also called pop-up headlights, but as you'll soon learn, not all pop-up headlights are necessarily hidden.
