A programmable visibility signal is a traffic signal that has a strobe light that can flash. It is usually separate from the main traffic lights and protrudes over or beneath them. It is used to avoid confusion. The programmable lights are also referred to as a “flashing” sign. These lights use a 12-inch Fresnel lens that is tinted to ITE standards. It combines the light output of two or more lamps to produce a uniform display of light. The original version of this traffic signal was first introduced in 1965 and is still in use in the United Kingdom and its Crown Dependencies and British Overseas Territories.

In addition, it can be designed to be square to make it easier to identify oncoming traffic.
