Emergency vehicle lights
Emergency vehicle lights are one or more visual warning lights that are fitted to a vehicle and used when a driver wishes to convey to other people on the road the urgency of their journey. They are also used to provide an additional warning when stationary, or when used by law enforcement as a way to signal a driver to stop. Emergency vehicle lights are also used to clear a path for emergency vehicles. When the police use emergency lights, they can be a signal that a driver needs to pull over. Emergency vehicles, in most cases, use red emergency lights. Examples of emergency vehicles who use red emergency lights are police vehicles, fire trucks, and ambulances. In contrast, blue emergency lights are often used by police officers. Besides police, other vehicles that use blue emergency lights are EMTs and firefighters. In some states like Texas and New Mexico, blue lights are used on construction or utility vehicles and tow trucks. Amber/yellow warning lights Amber/yellow warning li
