winkers

A winker is a type of flashing indicator light used on vehicles to signal a turn or lane change. Also known as turn signals or blinkers, these lights are a crucial safety feature in modern automotive design. They typically consist of a light bulb housed behind a colored lens, usually amber or yellow, that flashes intermittently. The flashing action is controlled by a flasher unit, which interrupts the electrical current to the bulb, causing it to turn on and off.

The primary purpose of winkers is to communicate the driver's intended actions to other road users, including other drivers, cyclists, and pedestrians. By activating the appropriate winker on the side of the vehicle where a turn or lane change will occur, the driver alerts others to their maneuver, allowing them to react accordingly and prevent potential accidents. Regulations regarding the use and visibility of winkers vary by jurisdiction, but they are a universally recognized signaling device.

Early vehicles did not always feature these dedicated signaling lights. Drivers would often use hand signals to indicate their intentions. The development and widespread adoption of winkers in the early to mid-20th century significantly improved road safety by providing a clear and standardized method of communication. Modern vehicles often incorporate advanced winker systems, such as LED lights for increased brightness and longevity, or dynamic indicators that sweep across the lens to further enhance visibility.
