What condition should illumination and signal lights be maintained in?

Illumination and signal lights should be maintained in a safe working condition to ensure visibility and safety in the workplace. Properly functioning lights provide necessary visibility for workers, helping to prevent accidents and injuries. It is crucial that these lights are bright enough to be seen in various conditions, allowing operators and pedestrians to navigate the work environment safely.

Maintaining lights in a compromised state, such as dimming them for energy savings, can jeopardize safety. Similarly, having them flashing intermittently or occasionally turning them off can lead to confusion and potential hazards. Therefore, ensuring that illumination and signal lights are always in safe working condition is essential for maintaining a secure work environment.
