Awasome Black Box On Top Of Traffic Lights References. Web then i noticed the black box camera (side on facing as if looking across all 3 lanes of the junction) but seeing as i got a speeding ticket last month, i don't intend to get any other offences under my belt. Web above the traffic lights was a small black box, has a small red dot light on it.
Do you know what the little boxes on top of traffic signals are? Web what are the black boxes on top of traffic lights? I see this at least once a day on here.
