In 1930s, when indicators lights were introduced to car, the familiar clicking sound came from the heating and cooling of metal as electricity went through the circuit.
But as technology change, they had to intentionally keep the sound.
A few days ago, the clicking sounded twice as fast in my car. And upon checking, one of my bulbs failed.
That early warning saved me from confusion and possibly from an accident.
It made me wonder…
For the most important things in life, health, finance, relationships, what’s is the signal to know if when something is not working?
