Re: All I want...
In the late seventies, my southern US hometown installed a new traffic light system that featured a 1"x2"x3" box hanging with each set of lights. Way too small for an industrial camera at the time, but if you flashed a particular speed strobe at it, the traffic lights would cycle. I was in high school. Had a lot of fun with that.
I've noticed similar boxes and tubes on many traffic lights and assumed they performed a similar function.
Or you could drive a firetruck.
