My first attempt at Illuminating the 1 inch dark space between the dotmation housing and dotmation screen.
I adhered 4 strips of black weather stripping foam (1 inch x 1/4 inch ($10 amazon) to the back of the game glass creating a light blocking box around the dotmation screen.
I added a washer to the two dotmation housing studs allowing the dotmation housing to slide back and be secured with enough room to accommodate the foam box.
I installed a white LED strip light ($10 Menards) to the top and sides of top box just behind the glass.
The results are promising, it could be brighter. More to come...
Update - Unplugged the fluorescent lamp and re-positioned the LED strip. More artwork revealed.
Now to get the colors right. Anyone know the LED equivalent of Fluorescent?
