Stop and go lights communicate when drivers should stop or proceed when moving through your car wash. They can be used in tunnels or touchless-automatic washes. Green light or an illuminated arrow tells customers it is safe for them to drive forward. A red light or an illuminated red x tells customers to stop because it is unsafe for them to advance. Many of the light fixtures featured in this category are designed with a swivel mount so you can point them in the direction that is easiest for customers to see as they move about your wash.
