A two-way safety sign is a type of safety sign that is visible from both sides. It is designed to be installed in locations where there is traffic or movement in multiple directions, such as on a corridor, staircase, or walkway, parking lots, roadways, and industrial sites.

A solar LED traffic signal light is a type of traffic signal that uses solar panels to power the LED lights instead of relying on traditional electricity sources. The LED lights are energy-efficient and durable, making them an excellent choice for use in traffic signals. These signals are typically used in areas where traditional power sources are not available, or where there is a desire to reduce energy consumption and environmental impact.
