  • activation of the visualizing element may emit visible light, wherein deactivation of the visualizing element may not emit visible light.
  • An operational condition may be also associated with both activation and deactivation of a visualizing element, meaning that the visualizing element may be operated intermittently in a flashing operational condition.
  • an operational condition may be associated with a wavelength of emitted visible light. Therefore, visualizing elements operated in the first operational condition may emit light of a different color than visualizing elements operated in the second operational condition. Additionally or alternatively, the intensity of emitted light may be associated with an operational condition. For example, visualizing elements operated in the first operational condition may emit light with a greater intensity than visualizing elements operated in the second operational condition, or vice-versa. A visualizing element may be also operated to gradually change the intensity from a low light emission, or no light emission at all, to a higher light emission and back to a said low light emission, or no light emission at all.
