S? IDENT CASE
H ave you ever wondered why the turn signal on your car makes the sound it does? The turn signal “click” dates back to the 1930s — and the turn signal itself dates to 1909. A man named Joseph Bell patented the electronic device that made the click possible, and in 1939, Buick began to incorporate the flashing and clicking turn signals into their vehicles. Buick, as it happened, was ahead of its time. Most car manufacturers were slow to use the technology. It wasn’t until the 1950s, when more people were buying cars, that clicking signals became standard in just about every new automobile on the road. Where does the sound come from? Well, in some cars, especially older models, the signals are generated by a thermal-style flasher. Electrical current flows through the flasher, which houses a bimetallic spring. When the turn signal is switched on, a current is sent through the spring, heating it up. The two metals in the spring heat up at different rates. As a result, they bend in a specific way. This bending does two things: It completes the circuit, sending a current to the “blinker” for a split second, and it makes a distinct clicking sound. This process repeats as you sit in traffic waiting to turn (or merge). In newer vehicles, especially those produced from the early ‘90s onward, you’re likely to find an electronic relay-style system. These devices are controlled using a microchip and an electromagnet. The chip regulates the electrical current that runs through the electromagnet. THE SOUND OF TURNING A Brief History of the Clicking Turn Signal Like the older style flasher, this relay completes the circuit to turn on signal lightbulbs for a split second while making the clicking sound. And interestingly enough, this sound is physical. There is a moving part in the relay unit making the noise as a current passes through it. Today, some new vehicles still use the electronic relay, but more vehicles have shifted to devices that are completely chip controlled, which means no moving parts. Instead, the clicking noise is produced electronically through either the driver’s side speaker or a dedicated speaker on the signal control unit itself, depending on the manufacturer. The new technology is not as exciting, but the click remains an important part of our daily driving experience.
insurance can negatively affect settlement payouts due to certain laws in
