Lite Brite: the toy where you have literally hundreds of pegs and "thumbtack" them into a lighted plastic box? I remember you had to put a black sheet of paper down so that when the pegs went it, the pegs lit up in the color they are. There were also templated black sheet so you could make nicer artworks.
They definitely were a fire hazard...I remember burning myself trying to prematurely change the light bulb. Whoever thought that a plastic box with a lightbulb and construction paper WOULDN"T be a fire hazard?!?!?!
Any of you guys remember the toy Night Lite? The jingle went "Nite Lite, Nite Bright, turn on the magical colored light" For some reason this commercial is stained into my brain, and I really hope that this site can get a hold of it and put it up.
Actually the light up toy is Lite Brite and you can go to youtube.com and watch the commercial. I had one when I was young. I was singing the song the other day and my 19 year old son said "WHAT are you singing? You come up with some weird songs." Haha
