They appear to be just like normal signals, but without sections I do like the look though The time countdowns on the right of the signals are green, left are red... but why not just use 1 LED?
I was more or less curious about light sequence and if these were solely running on timers or if there was any type of detection that I was missing.. I didn't spot any loops or signs of video when i was looking. The 2nd pic from the bottom might have a controller box on it
These lights look cool, but also appear to be akin to something you'd find at IKEA. Modern design cheaply made. The mast/pole setups don't appear to be much more than 3" rigid with a sweep in it, so I don't imagine these things being too substantial on that front either. (The first thing I thought of when I saw them was Tomorrowland at Disneyland. )
