Kiertovilkkaisin

Kiertovilkkaisin is a Finnish term that translates to "rotating blinker" or "rotating beacon." It refers to a type of light signaling device commonly used on emergency vehicles, construction equipment, and other vehicles requiring enhanced visibility. These devices emit a flashing or rotating light, typically in bright colors such as red, blue, or amber, to alert other road users or pedestrians to the presence of a potential hazard or a stopped vehicle.

The mechanism behind a kiertovilkkaisin involves a light source that is either physically rotated or uses a system of mirrors and lenses to create the illusion of rotation and flashing. Older models often used a bulb that rotated on a motor, while newer versions frequently employ LEDs that can be programmed to flash in various patterns. The primary purpose is to capture attention and convey a sense of urgency or caution.

In Finland, the use of kiertovilkkaisin is regulated by traffic laws. Red and blue lights are generally reserved for emergency vehicles like police cars, ambulances, and fire trucks. Amber or orange lights are typically used by slower-moving vehicles, such as those involved in road construction, maintenance, or breakdown assistance. Proper and legal use of these signaling devices is crucial for maintaining road safety and preventing accidents. The term itself emphasizes the visual nature and the cyclical operation of the light.
