            SIGNALMAN LIGHTING FEATURES
          
        
        
          One of the unique features of the SignalMan and its near relative,
        
        
          the LocoNet Control Point (LNCP), is the ability to set up special
        
        
          lighting effects using LEDs. Four options are available: Fade, H2
        
        
          Flicker, Tumble Down, and Strobe. A fifth special effect (off) simply
        
        
          gives LEDs a basic on/off mode. Default for all effects is off.
        
        
          
            Fade:
          
        
        
          Allows LEDs to mimic the appearance of a prototypical
        
        
          signal lamp with both a fade-up during turn on and a gradual
        
        
          decrease in brightness while transitioning from on to off.
        
        
          
            H2 Flicker:
          
        
        
          Emulates a searchlight signal’s unique red flash during
        
        
          transition. US&S H-series searchlight signals include a color vane
        
        
          which rocks back and forth in front of the lamp mechanism. The
        
        
          red lens is located in the center position between the green and
        
        
          yellow lenses. When observing a searchlight changing between
        
        
          green and yellow, there is a brief flicker of red as the lens vane
        
        
          rocks between those two colors. This effect is especially notice-
        
        
          able at night.
        
        
          Configuration of multiple heads on the same mast using the H2
        
        
          Flicker is also possible.
        
        
          
            Tumble Down:
          
        
        
          This mimics the motion of a semaphore armmov-
        
        
          ing from a permissive indication to stop, a unique feature found
        
        
          in B&O color position light and Pennsy position light signals.
        
        
          Combined with the fade effect, this can be particularly effective in
        
        
          establishing a prototypic signal appearance.
        
        
          
            Strobe:
          
        
        
          Not only can the ports on these boards be used to drive
        
        
          lineside signals, they can be used for special lighting effects of sce-
        
        
          nic items such as lights on a radio tower, emergency vehicle, or sim-
        
        
          ply as an attention-getting device on the fascia of your railroad. The
        
        
          strobe speed and length can be set in the decoder programming.
        
        
          JimDuncan used the strobe lighting feature on the live steam rail-
        
        
          road project to bring attention to the employee call lamp on the
        
        
          side of a building at a control point.
