The function of lighthouses is not just to warn sailors of a potential danger. They also enable them to find their position. This is done by not only making sure that the projected beam is highly visible but also making it distinct from any other lighthouse beam.

The most important way of making the beam distinct is to vary the pattern of flashing light so that it is unique to a particular lighthouse.

The Light chart uses a microprocessor to control the flash sequence of each light.

A unique miniature optical system acts as a light pipe transporting the light to the face of the chart , blending in seamlessly without impacting the original detail.
