This was my wall for the grad show. The middle one was the push button light box that was built by me with all the lights and print. Print was Lexan Day/Night [C/W/C] Reverse. The light was 12v LED light that can only be lighted with 12v battery. I wanted battery because I didn't want any wires to show out of the box. On the left of the box, it tells you specific details of the lighted section. Total 4 buttons and they were successfully lighted.
