The importance of emergency vehicle lights cannot be overestimated. These devices are literal lifesavers that provide first responder, construction, and utility vehicles with the means to warn travelers to decrease speed or move away from hazardous road situations. While there are many similarities regarding emergency vehicle light usage among the United States, the laws regarding the kinds and colors of lights are not uniform. Vehicle light requirements vary greatly from state to state.
