Many times there is a need to manage vehicle flow through traffic lights, but in some streets that turn out to be narrow, the vehicle lanes can be 1 or 2, a clear example is the historical centers of many cities. In those cases, the installation of the structure of a conventional traffic light would hinder the sidewalk due to the need for a robust base, in addition to running the risk of being impacted by some high-rise vehicle due to the size of the visors.

Sinowatcher created a solution for this problem and it is the Mini traffic lights. These perform the same function of changing lights as a conventional one, but with its compact and hermetic design, it allows to save space at the time of installation since, being lighter, they require less structure and, being small, avoid the impact of vehicles (see high-rise buses).
