ABSTRACT:
A novel lighting display system for numerous uses consisting of the following members. A mounting board containing two channels across the boards length, each channel carrying one electrical conductor; and plastic numerals, letters, or other characters, which when inserted into the boards channels are securely attached to the board, come in contact with electrical conductors in the channels and become illuminated. The plastic characters are constructed by encasing miniature light bulbs, mounted in parallel electrical circuit on a printed circuit board, in a plastic material. Various characters can be combined to form an illuminated message, word, or series of numerals.
