Look at the reflective border on these signals!
I'm not sure if you can tell but the reflective border is GREEN!

I've got a few more of those saved on Google Maps, here's two examples in Sioux Falls, SD:

I'm pretty sure those only light up pinkish when the light is red

I did not notice that. That's even more strange come to think of it, I've never seen or heard of this, has anyone else?

[jakeroot]

I guess as far as negative-contrast background go, we've now officially seen them all. Yellow borders in most states, a few white borders in PA, and now FYG in Mass.

Orange?

I knew I was missing one. I'm sure it'll pop up soon enough.

That's the most amount of supplemental signals that I've ever seen at an intersection in Texas.

I'd like to see these used nationwide, they seem like an effective tool and could supplement existing safety features at other road-rail locations as well, such as where you see "NO LEFT/RIGHT TURN - TRAIN" illuminated signs.

[ErmineNotyours]

Just saw this today: supplemental right turn arrow that flashes yellow when the main signal is green.  Why?  If the main signal is green and the pedestrian signal is not activated, why does it have to flash yellow?  Maybe they want to mimic right turn yields, or add extra safety for jaywalkers.  I think they thought that left turn signals flash yellow, so the right turns should flash yellow too.

Edit: They appear to use the same phasing as the left turning lights going the opposite direction.  It's simpler to just use the same phasing, but it's still wrong.

[steviep24]

This is a fairly new installation for NYSDOT. For some reason they used mast arms for three of the four legs of the intersection and use span wire for the fourth leg. Doesn't look right.

The signal I posted also has right turn FYA.

This can give more flexibility in the protection of pedestrians across that leg of the intersection. The pedestrian phase can be activated concurrent with the adjacent through green, but turning traffic can be held red during the WALK phase. Such operation allows the pedestrians a protected start, which gives the turning drivers greater visibility of pedestrians crossing. Jakeroot has previously posted a few examples of this from Washington state (Federal Way, WA?) in other threads. You'd be hard pressed to achieve a similar isolated operation of a turn lane using a green ball while also maintaining compliance with the current MUTCD.

[SignBridge]

New York City is using FYA's to protect crosswalks and bicycle lanes. It's not what FYA was originally created for, but it might be an additional effective use of FYA.

These yellow bordered new backpaltes are everywhere, even PA is using them:

In the photos above, the borders look lime-yellow, the same color that some fire trucks used to be.

[RestrictOnTheHanger]

New York City is using FYA's to protect crosswalks and bicycle lanes. It's not what FYA was originally created for, but it might be an additional effective use of FYA.

NYC is also starting using FYA (the full 4 section) at for some lagging turns onto highway service roads where yielding on the initial circular green is problematic.

Example of such intersection, but the latest setup hasnt been updated on streetview

Yeah, Federal Way has quite a few. Auburn, WA (same city as ErmineNotyours's example) has quite a few as well.

Here's some videos I've made over the years (first from Federal Way, second from Auburn, third from Bellevue) (all WA):

There's a right-turn signal that was installed on Cornelius Pass Rd in Hillsboro, Oregon with its intersection with Evergreen Pkwy. The signal faces northbound traffic on Cornelius Pass Rd. (https://www.google.com/maps/@45.54627,-122.8995965,3a,75y,1.27h,87.32t/data=!3m6!1e1!3m4!1skTW20AEW-pOUKetlC3DaAw!2e0!7i13312!8i6656). The signal flashes yellow when through traffic has green except when either the crosswalk or bike signal is activated. The only time it shows a green arrow is when left-turning westbound traffic on Evergreen Pkwy have a green arrow.

Oregon allows bicyclists to proceed through a red light if it uses vehicle detection and fails to detect their bicycle and display a green light after one full cycle of the traffic lights at the intersection (ORS 811.360 (2)). Because of this, a FYA appears to be the correct indication so right-turning traffic knows it may have to potentially yield to bicyclists legally proceeding on the red bicycle signal.

Not to be nitpicky, but those adapters are actually made by 3M. McCain has never produced 8-inch PV adapters as far as I know.

Yesterday, I made a right turn on red at this intersection.  I had just come out of the gas station RIRO you can see a bit of on the bottom-right of the screen.  I was surprised that there wasn't a "NO TURN ON RED" sign because of how awkward the turn was.  I noticed that oncoming traffic was stopped and Milton Ave had opposing leading lefts.  I looked for approaching trains, and when I saw it was clear, I crept past the tracks and saw the green arrow for Milton Ave eastbound, so I made the turn.  Looking at the Street View now, it looks like I may have not cleared the tracks like I thought I did after all.

Many similar situations near me do have "NTOR" signs, though there's quite a few (such asthis one) that have no such signs, and appear very similar to your example (though sometimes with two tracks). Major difference being, no "do not stop on tracks" signage at my example. It is almost certainly one of the newest crossings built in my area.

I suspect the "do not stop on tracks" message is mostly for those who are going straight, to keep people from stopping too late. For people turning right (or left), there's some expectation that you might stop on the tracks a hair, especially if yielding to cars or pedestrians.

I found this extremely rare 12-inch Marbelite model L signal in Philadelphia, PA. Anyone know the history behind this, I only know what the model is, because a few collectors on Youtube told me about it's brief history after I gave them Google Maps SV links. They say that this type L head was a predecessor to Marbelite's last-gen 12" head, most collectors nickname this the prototype signal:
