Sarcastic Secret: Signal Lights
By Chad Upton
Tickers, blinkers, indicators and flashers. They have many names, but only one purpose: to let people know your car is about to change course.
In most vehicles, a lever on the steering column moves up or down to activate flashing lights on either side of the car.
I suspect a lot of people don’t even know their car has such lights, but they’ve been standard on cars since cars.
Maybe it’s a confusing concept, so I’ll try to explain it in a straight forward manner: if you’re about to turn your steering wheel, put these lights on first.
I find that some people use signal lights like the horn. They know they’re there, but they only use them when they need you to move.
Most vehicles also have a way to put all four blinkers on at the same time. The vehicle manual may refer to these as “four way flashers” or “hazard lights” but a lot of people know these as “park anywhere lights.” Their understanding of this feature is, when you want to double park, park in a fire lane or any other no parking zone, these flashing lights give you temporary immunity from parking regulations.
In all seriousness, signal lights first appeared on cars in 1907, but weren’t patented until 1938. Some cars from the 1920s to 1950s used solid (non-blinking) retractable lights on the sides of the car, called a trafficators.
