Did anyone notice the device attached to the visors on these signals? Any idea what it is? On each light, there is a wire leading to the device.

Re: Arch Rd, Royersford PA
could they be cameras to catch people who go across when the signals are on?

They do look like CCD's, but why two of them?illinoistrains wrote:could they be cameras to catch people who go across when the signals are on?

Radiant heaters to melt snow and ice?
Otherwise LEDs produce so little heat that the lamps remain obscured.
Detectors to detect if light is blocked by snow and ice?
But if blocked, too late to do anything about it.

You know... I thought about that too. We have a significant problem here with that in the wintertime with LED traffic signals. It is certainly concievable.Robert_Gift wrote:Radiant heaters to melt snow and ice?
