We got rid of pop-up headlights because they were causing pedestrian deaths, but I don’t think we’ll do anything about these monstrosities because not only are they deadly, they’re not fun. And our regulators want to prevent fun more than they want to prevent death.
The United Nations Economic Commission for Europe’s 1998 Global Technical Regulation Number 9 deals with pedestrian safety sets out how countries should test the pedestrian safety of vehicle exteriors. The U.K.'s Individual Vehicle Approval framework, which is based on the aforementioned Global Technical Regulation, limits the size and presence of sharp edges on any surface where a pedestrian or cyclist is likely to impact in the event of a collision. According to the U.K. regulation, protrusions greater than 5 mm (0.195 inches) must have a radius of at least 2.5 mm (0.098 inches), and further rules prohibit protrusions on which pedestrians could get caught in the event on an impact. These and other regional E.U. laws made it prohibitively difficult to engineer pop-up headlights into a vehicle.
They weren’t killing people, I don’t think, but they were unnecessarily sharp protrusions. They can still be used, but you have to make them roundish and smooth, which is tougher to accomplish with a flush-with-hood-look. It’s more that to meet EU regulations, they would look uglier.
I think the bigger issue isn’t death but simply that you can get caught on them, instead of rolling over the vehicle, which causes less harm.
Not quite right. They became common due to a combination of aerodynamics and lamp height restrictions. Especially in the US, which used to require one of a small list of sealed beam designs which weren’t at all aerodynamic. They are still technically legal, but difficult to integrate with protrusion restrictions. The US also dropped the sealed beam restriction decades ago, so there wad no point in trying.

I hadn’t heard this before. How were pop-up headlights killing pedestrians?
A pedestrian’s body doesn’t slide up the hood obstruction-free. It gets mangled by a sconce.
Thanks for the explanation.

I thought we ditched popup headlights because having a piece of critical illumination on a moveable body panel was a bad idea?
