What color is NOT used in the lamp of a funeral procession escort vehicle?

In the context of funeral processions, escort vehicles typically utilize specific colored lights to signal their presence and ensure safety on the roads. The color white is not used in the lamp of a funeral procession escort vehicle. Instead, red, blue, and amber lights are commonly employed to indicate various types of vehicles and their functions. Red is often associated with emergency vehicles, blue can indicate law enforcement or emergency services, and amber is frequently used to warn other drivers of slower-moving or stationary vehicles, such as those involved in a procession. Understanding this color coding helps reinforce the proper recognition of different types of vehicles on the road, especially in sensitive situations like funeral processions.
