Traffic light code SI 07
A traffic light is a 3-color light that is installed at intersections, entrances and exits of passages and other places where the traffic load can come from several directions and indicates the priority of traffic. In fact, this type of traffic equipment uses three standard colors (red, yellow, green) to determine the right of way.

If the light is green, drivers have the right of way.

Yellow means that the end of the traffic is approaching for drivers and they should cross with caution

Red means that the car is standing behind the pedestrian crossing

Usually, the red light in this device is orange-colored and the green light is blue-colored, and people who are color blind will not have a problem.

Types of traffic lights include:

Three-way traffic light
Flashing traffic light
Reverse traffic light
Pedestrian crossing traffic light
LED traffic light
Solar traffic light
Smart traffic light

In the 1930s in Iran, as the volume of cars increased, traffic lights were used in Iran, but over time and with the advancement of technology, one of the newest of these lights is the solar light.

Solar traffic light
Traffic lights are used to maintain a modern city away from traffic. Among the numerous advantages that this product has over other traffic light products is the lack of electricity because it is a structure that works without electricity and receives energy through a solar cell. This light can work for up to 7 days and nights through absorbed solar energy. And it saves on urban electricity consumption.

The advantage of solar traffic lights is that they do not require excavation for their trenches and do not cause delays or traffic jams. As such, wiring or electrical work must be done on site and any potential disruptions must be re-checked to minimize them. Since no work is done on the site infrastructure, solar traffic lights can be easily transported on a trailer and can be activated within minutes of arriving at the site.

To increase the visibility of traffic equipment, it is important to install them at a suitable distance from urban lighting equipment.
