EMERGENCY FLASHER Meaning and
Definition
-
An emergency flasher, also known as hazard lights or hazard warning lights, is a signaling device installed in vehicles to warn other road users of a potentially dangerous situation. This device consists of a pair of synchronized blinking lights that flash simultaneously, typically located at the front and rear of the vehicle.
The purpose of the emergency flasher is to alert other drivers to the presence of a hazard or emergency situation, such as a vehicle breakdown, accident, or any unexpected event requiring immediate attention. When activated, the lights flash at a regular interval, usually in a simultaneous and continuous manner, making the vehicle more visible to surrounding traffic in low light conditions or during inclement weather.
Emergency flashers are operated by a switch or button located within easy reach of the driver's seat. They are designed to be used in conjunction with other warning signals, such as honking the horn or activating other vehicle lights. The intention is to warn approaching drivers to exercise caution and be prepared to slow down or maneuver around the affected vehicle.
The use of emergency flashers in various countries is subject to specific regulations and laws. In many jurisdictions, it is mandatory to turn on the hazard lights when a vehicle is stationary due to an emergency or breakdown. Understanding how and when to use emergency flashers is crucial for drivers to ensure their safety and the safety of others on the road.

Etymology of EMERGENCY FLASHER
The etymology of the word "emergency flasher" dates back to the mid-20th century and is derived from the combination of the words "emergency" and "flasher".
The word "emergency" originates from the Latin word "emergentia", which means "an arising, an emergent state or condition". It entered the English language in the early 17th century and refers to a sudden, unexpected, or critical situation requiring immediate action or intervention.
The term "flasher" comes from the verb "flash", which itself has Old English and Scandinavian roots. "Flash" originally meant "to glitter, sparkle, or emit sudden bursts of light". However, its modern usage as a noun describes a device or mechanism that produces brief, intense bursts of light.
When combined, "emergency flasher" refers to a device installed in a vehicle that produces intermittent bursts of light to signal an emergency situation.
