How many lights are equipped on a TF-2 unit?

The TF-2 unit is designed to enhance visibility and safety during various operations, and having four lights is optimal for providing thorough illumination. The arrangement of four lights allows for better coverage from multiple angles, reducing shadows and ensuring that all areas around the unit can be seen clearly. This is particularly important in environments where precision and safety are critical, such as in electrical power production and maintenance tasks. The design's efficiency and effectiveness in enhancing operational safety through adequate lighting are key reasons why four lights are included on the TF-2 unit.
