Headlight Wipers
There were a lot of interesting safety features that came out of the 1980s and ’90s, but perhaps the most unique thing was headlight wipers. You’d generally see these on more expensive cars from the era. Like a Mercedes or a BMW, and they helped with visibility on the roadways. But the units were expensive to replace and most drivers never needed to use them on an average drive (via Hot Cars).
Additionally, the development of advanced headlight systems, such as LED and xenon lights, provides enhanced visibility without the need for additional cleaning mechanisms. While headlight wipers may have been a practical and quirky feature of the past, they have largely been phased out in favor of more advanced and maintenance-free headlight designs.
