In the early days of motoring, everything on the car was manually controlled, and we are not just talking about the transmission or the windows. We mean everything; like turning the wipers manually with your hand, cranking the engine by hand (and we don’t mean twisting the ignition key), even lighting the head lights yourself – with matches!
In 1903, cars used paraffin lamps as headlamps, which is merely a fancier version of a household candle.
Electric headlamps were introduced in 1920 and since then, the automotive lighting technology has progressed to include Xenons, LEDs and now – Audi’s laser headlights.
