A FLYA I found with no green arrow section.

Seen a lot of those in the St Louis area. I don't think they're that uncommon.

They aren't. I have seen plenty of them in the greater Atlanta area. Sometimes the bottom section is a bimodal green/FYA, but other times there is no capacity for any sort of green arrow.

They're fairly common in the Milwaukee area, especially where one direction of a street has a flashing yellow arrow that has a green arrow section, but the other doesn't have a protected left turn lane.

Here is one SC uses a lot.  Two flashers that flash vertically which seems to be the norm in SC, from what I heard here and have seen driving the state.

Here's something you don't see every day: Brand-new 8" arrows! This signal is most likely temporary, being part of the temporary access to the ferry terminal during construction, but it's still quite a strange sight. Plus, the visors are installed sideways, which I'm sure is an attempt at limiting the field of view (though not a particularly common way of doing so around here).

Wow this is unique ! I think the signal plans for this project are public online somewhere, I remember reading them. We'll see if it stays

Looks "continental".

I think the engineers put this reflective backplate on...backwards?

Reminds me of King County, WA, and a few cities within it, where the backside of backplates are very often solid yellow (in addition to the yellow signal housings):

Not sure I have seen one with a reflective backside though.

That HAWK signal has yellow backplates which are not MUTCD compliant. Though the requirement for black backplates is almost irrelevant today with the yellow reflective edge lines.

Also how anyone could have installed those backplates backwards in Caps81943's post is beyond belief.

It's at least the second signal in Renton with all-yellow backplates. The other is downtown on 3rd and Burnett: https://goo.gl/maps/mxkkkUKccKvmR5gg8

I'm 99% sure there is another somewhere; erminenotyours (resident Renton expert) may know where it is.

Totally agreed though, the dull black requirement seems pretty pointless, especially with some municipalities installing very thick retroreflective yellow borders (thinner borders are more common around here).

[Big John]

^^ MUTCD allows 1" to 3" yellow reflective tape thickness.

[SignBridge]

I wonder if the next edition of the Manual will eliminate the requirement for black backplates given the new reality.

Thought you signal people might be interested in these signals at this intersection...not that I can tell what's interesting or not...

I do not see anything in the national MUTCD prohibiting reflective backplates on hybrid beacons.  Illinois however specifically prohibits reflective backplates on hybrid beacons in the state MUTCD supplement.

Looks like a pretty interesting intersection to me. Lots of old equipment in use, though I don't know the names of them.

The "round" lights are 1950's era Streamline signals made by General Electric.  Personally, those were my favorite since they were not made too long and they had an unusual look to them vis a vis other signals.

I love the look of the double yellow. Portland uses them on bike signals, we may switch to that too.

Yeah, me too. It's very Canadian.

I've seen similar all-yellow bike signals here too, here's an example in Redmond.

[Big John]

^^Odd 12-8-8 bike signals.

Good point, not sure I've seen 12-8-8 bike signals before.

Those are GE Streamlines. I actually live near these and could get photos if anyone wants.

NJ always had signals with heads over the opposing lanes of traffic.  I never understood that reasoning until I moved down to Florida where the state here follows the MUTCD hanging only the needed signal heads directly in front of the driver.  That created a problem once I had semis in front of me blocking my sight of the signals.

The above location has the two sided double back to back heads as you can see which allows you to have an alternate view of the signals orientation if a large semi is the vehicle ahead of you.

IL and CA have something similar, but near right side side mount signal heads instead.

Too bad NJ is phasing out the median mast arms you see here for more traditional mast arm set ups, but I like this set up here. I don't like the street blades though showing the cardinal directions here though due to the inability to turn left or right here restricted by the NO TURNS sign posted.

Edit: another signal assembly up the same road from previous location shows the removal of opposing side mast arm from median to comply with the latest MUTCD.

I like those setups that have some near side and vertically mounted signals. So many states just use far side overhead signals, and nothing else.
