Flashing lights are a common warning signal used in many contexts. The term 'flashing lights' can refer to two distinct types of devices: BLINKERS and strobes. BLINKERS, also known as turn signals, are 8-letter devices that are typically found on the exterior of vehicles. They are used to indicate when a vehicle is turning or changing lanes. Strobe lights, on the other hand, are 7-letter devices that emit a series of rapid flashes of light. These are often used in emergency situations, such as police cars, fire trucks, and ambulances.
