Here is a signal that uses two side by side heads rather than spaced apart. Plus it's a an old mast arm to boot that is why the heads have to be that way here.
No it's not a Google double image either.

I found a functioning set of 4-ways in La Rue, Ohio.  I can't believe this are still in use!

How about these odd looking cutout visors.

Unrelated; I forgot just how much of a dead-ringer those old New Jersey horizontal signals are for Japanese signals, at least in terms of their placement and orientation (especially the back-to-back placement). Japanese signals are normally silver, with 250mm lenses, but otherwise it's just like Japan.

Looks like those are Marbelite signals, I believe those "fat cutaways" are exclusive to their signals, save for ones used as replacements on other heads of course.
It's all fun & games until someone summons Cthulhu and brings about the end of the world.

I also collect traffic lights, road signs, fans, and railroad crossing equipment.

New Jersey beats both California and Illinois here with three left turn signal heads for one left lane protection using a four section permissive signals. Usually two are only used for a single lane turn, even in New Jersey.

^^ Traffic can't go straight, so I think flashing yellow arrows would be more appropriate.

A similar setup closer to home in Cambridge, MA was converted to a FYA setup (albeit with seperate 3-section signals) - previously, it used to use both steady left and right green arrows while the oncoming traffic had a circular green.

The steady left/right green arrows while oncoming traffic has a circular green setups still exist in some parts of Boston, like at Everett St at Soldiers Field Rd's jughandle. I once saw a driver on the Everett St approach get off-guard at this intersection - despite having green arrows for both left and right, the driver didn't expect oncoming traffic to also have a green as well.

There is also this setup in Brooklyn at Atlantic Avenue & Euclid Avenue, but unlike the CA or MA examples, this example is two, one way streets intersecting with each other. It used to be circular green, but changed to a double FYA setup in the 2020s.

At what point in history was it ever okay for there to be a left turn green arrow opposite a solid green orb? That completely defeats the point of a green arrow.

I've seen setups like this (I think...they may have been green orbs), but the oncoming traffic has a flashing yellow orb, not a solid green orb.

SignBridge

I agree jakeroot. The whole principle of a green turn arrow is that it gives you an exclusive right-of-way for that specific movement. The signal will not (should not) clear any other movement that conflicts with the arrow movement and that includes pedestrian signals. A pedestrian will not (or should not)  get a walk signal if it conflicts with the arrow movement.

Big John

I believe pre 1971 MUTCD allowed an all arrow indication that meant allowed movements and not protected movements. There were instances after that the signal indications were changed from 2 green arrows on a 4-section signal to a green ball and a blank section.

I noticed a single aspect signal head on the same assembly as a three aspect head. Looks like NYSDOT added a bimodal arrow next to a regular signal. Strange for a NYSDOT install.

Reminds me a bit of the vertical signals in Japan, just with the arrow in the opposite place:

What kind of a set up is this here? The FYLA is on top maybe?

Sign says Left Turn Yield on Flashing Red Arrow After Stop.  Looks like Delaware is trying a left turn system fashioned from a HJAWK system.

jakeroot

I can't find any permissive phasing in Google Street View. But I agree, looks like it might be designed to have adjacent flashing red arrows.

It's not "fashioned from a HAWK". It's a permissible signal head arrangement in the MUTCD.

DE really needs to drop the flashing reds and get on board with the FYA. Seriously.

This That four head signal must be one of the most rarely-used MUTCD-permitted features, of any chapter. Up there with the large painted "yield ahead" triangle.

Isn't the flashing red left turn arrow also a thing in Maryland? Or have they abandoned that for the FYA?

My understand is that Maryland continues to use the flashing red arrow alongside neighboring Delaware.

I thought I saw a flashing red used in Michigan before as well

Here is still a 3M that has yet been phased out in use as of last Summer.

https://maps.app.goo.gl/R8cWT53yaWQ2gkrS8
Another signal with a 3M from past August.

Ironically the second example is at a NJDOT maintenance facility driveway.

Another rare find. The Google imagery captured the fiber optic arrow in a yellow phase in the four section permissive signal head.
