Diamond
grade fluorescent tape ensures sign  can be illuminated at night by
the oncoming traffic's headlights. In addition, the LED-DOT becomes
illuminated with its own internal high intensity amber LED's from
Hewlett Packard for unsurpassed legibility The LED-DOT uses a rectangular shaped dot which hinges on a vertical axis. The rectangular dot provides a minimum of 16% more colour in a given space than round discs. This unique shape provides unsurpassed legibility in a minimum of space. In addition, the LED-DOT vertical hinge, as opposed to competitive horizontal hinges, provides a positive flipping action without any flutter vibration. This results in greater legibility, plus allows faster message updates. In addition the very low current drain complements the solar energy system.
