Intelight ESB interior

This is inside the ESB head. The lighting panel is a software controlled LED array. Power for the LED and software wireless input comes in on the board on the left. The board on the right is for the photocell, and built in detection cameras. Mine didnt come with cameras.

Software is used to turn on and off rows and columns of LEDs in the array to "program it" so only certain lanes can see it. This makes the old 3M and McCain programmable heads that used special tape and a series of lenses obsolete.

Theres more room in here for extra boards for communications and homeland security features.
