Why Are There No Pop-up Headlights Anymore?

[JuliaAnn]

The reasons for the absence of pop-up headlights: Pop-up headlights on cars are highly aggressive and significantly impact road safety, leading to a complete ban on their use. Pop-up headlights refer to a hidden headlight design where the headlights are recessed inside the vehicle's front hood when turned off and flip upward when turned on. The hazards of pop-up headlights: 1. Increased drag coefficient—streamlined designs are more effective at reducing a car's aerodynamic drag at high speeds, whereas the protruding nature of pop-up headlights disrupts smooth airflow, thereby increasing the drag coefficient. 2. Impact on road safety—these headlights can cause secondary injuries. At high speeds, the sharp-edged design of such headlights could lead to unimaginable consequences if they hit a pedestrian. Therefore, the disappearance of these headlights is not due to a lack of popularity but rather safety concerns that led to their prohibition.
