Warning lights are devices used to alert people of potential danger or hazardous conditions. FLARES and beacons are two types of warning lights that are commonly used. FLARES are a type of warning light that is typically used in emergency situations, such as when a vehicle has broken down on the side of the road. Beacons are another type of warning light that can be used to indicate the location of an emergency vehicle or to mark a hazardous area. Both FLARES and beacons are important tools for keeping people safe in potentially dangerous situations.
