Intelight is still kind of obscure compared to companies like McCain and 3M. 3M already closed up shop on their programmable head, and McCain will eventually follow. Both the optical tape PV signals are obsolete now with the advancements in computers, steerable beam technology, LEDs and other things.
The inside of the Intelight is very high tech. Alot of circuit boards and electronics for built in cameras (don't think mine has the cameras though) and software to program the signal. They truely are like no other traffic signal.
I'll take good pics and video of everything when I get it. Should be here tomorrow afternoon.
