‘Rotadipper’ moveable directional headlights, as seen on this '66 Mini back in the 1960's, that turned with the steering to “enable drivers to see round corners.”
("The 1967 Citroen DS series 3 first introduced directional headlights to a mass-produced car. This design had four headlights under a smooth glass canopy and the inner set swivelled with the steering wheel. This allowed the driver to see "around" turns, especially valuable on twisting roads driven at high speed at night. The directional headlamps were linked to the wheels by cable. Behind each glass cover lens, the inboard high-beam headlamp swivels by up to 80° as the driver steers, throwing the beam along the driver's intended path rather than uselessly across the curved road. The outboard low-beam headlamps are self-leveling in response to pitching caused by acceleration and braking. Because this feature was not allowed in the US a version with four exposed headlights that did not swivel was manufactured for the US market. Citroën was the first to mass-market adaptive headlights.")
