Let there be light
Emergency vehicles use various types of warning lights to alert other drivers and pedestrians of their presence and need for priority movement. Some common types of emergency vehicle warning lights include:
- Flashing lights: This is the most common type of emergency vehicle warning light. Flashing lights are typically either red, blue, or a combination of both colors. They are designed to be highly visible and catch the attention of other drivers on the road.
- Strobe lights: These lights use a high-intensity strobe effect to grab attention and warn drivers of an emergency vehicle. Strobe lights are often used in conjunction with flashing lights to increase visibility.
- LED lights: LED lights are becoming increasingly popular for emergency vehicles due to their energy efficiency and longer lifespan compared to traditional lighting options.
- Rotating lights: These are older-style warning lights that use a spinning mechanism to create a flashing effect. They are not as common as they once were, but they are still used on some emergency vehicles.
- Wig-wag lights: These lights alternate flashing between the left and right sides of the vehicle, creating a wig-wag effect. They are often used on emergency vehicles that need to quickly move through traffic.
- Barricade lights: These are smaller lights that are used to mark off a particular area or direct traffic around a scene. They are typically yellow or orange and are often battery-operated for easy portability.
Note that the specific types of warning lights used on emergency vehicles can vary depending on local laws and regulations.
