night light sockets with the word "BLUE" cast into them, Because when they were built, that is the color the Navy thought would preserve night vision... The realization they were wrong may have been early in 1943 and changed to red but they just replaced the globe not the whole fixture.

[@paulfarace9595]

Bingo!!!!❤

[@matto5105]

THIS is a great esoteric detail. Thanks!

[@bigjd2k]

In the UK they used ruby red light bulbs. The bulbs themselves are made from a gorgeously dark red glass, very thick and heavy. I got a box of them on eBay years ago! There are more on sale now! They have “property of HM Government” stamped on them. They don’t produce much light but it’s deep, rich red!

[@DrewMacGregor]

Early in the 40s, they believed blue lights were better for night vision, and so they were called blue lights and had the blue lights in the fixtures. It was later they determined that red light was better, but the lights were cast already.

[@louisvillaescusa]

In the theater, back stage running lights are usually blue. That's because if any light spills out in view of the audience, blue is less noticeable than red. Since there is a long history of sailors also working backstage on the rigging in theaters, that might be why they chose blue first.

[@VEC7ORlt]

Believed? Doing an experiment must be an insurmountable obstacle. Strangely enough a lot of work on color theory was done way way before that, so smells like BS.

Blue lighting is used for night vision in some spaces aboard surface ships because red affects the visibility of the radar and computer screens. Also, blue lights were typically used at refueling-at-sea stations aboard surface ships.

[@paulfarace9595]

True for today, but not so in WWII subs.

[@JoshuaTootell]

I wondered why they used blue in CIC instead of red. Just never thought to ask.

[@dennisfariello4852]

Something else blue light related. Surface ships have three stern lights. A regular white light (which can be set to bright or dim) a blue "convoy" stern light (designed to be visible from the ship directly astern and no further) and a "wake" light which, believe it or not, is to illuminate the wake. I am not sure why, but I'm thinking it also has to do with convoy operations. Might be even less visible at a distance than the blue convoy light? Perhaps used in heavy weather?

[@scottfarnham2717]

I was wondering how they safely changed the bulbs. I can't imagine being in a sub while being depth charged especially when the lights go out. It would take nerves of steel. Submariners are brave souls!

[@davidlewis3433]

On the nuclear submarines I served in, our main lighting was fluorescent and some of our emergency lighting was incandescent. We had modified battle lanterns hooked up to emergency lighting bus. Just to reinforce the peculiarities of submarine adaptation, the fluorescent tubes in our lighting had what was called depth charge clips. Meant to keep the tubes from unseating. By the time we came along, I seriously doubt even a modern boat would survive a depth charge, make that a depth bomb. No doubt a nuke.

[@airplaneengine]

About 20 years ago, I bought one of those pigtail socket extensions from a surplus store here in the Minneapolis/St.Paul area. It looks just like that in the video. I remember they had a whole box of them (now long gone) and I dug through and found one that the short rubber cord wasn't cracked on. I honestly didn't know what it was really made for other than I made use of it in a basement backroom to lower the bulb down below some duct work. It's still installed in my backroom today. Let me know if you want pictures of it, assuming it really is a submarine pigtail.

Blue was also used because it did not affect night vision. But, on surface ships blue light stands out like a sore thumb. It is even more visible then white light.

[@MrJeep75]

So did red

[@jochenreichl796]

You don't need to check for all kinds of hoses, that won't perfectly fit anyways. Go to any local shop that has a waterjet cutter. Get a sheet of cellular rubber, and have rings cut out. That will have the right dimensions and will look close enough.

[@kmoecub]

Agreed. I very much doubt that the rings were made from hose to begin with. There's no need for cording to reinforce the rubber for this application, and during wartime both rubber and cord are not going to be used if not absolutely required.

The examples that I posit still exist are the ones that I'm sure many, many serviceman pilfered, whether it be for souvenirs, or simply to use at home in their workshops, as, save for the rubber doughnut, they are still ordinary medium base bulb found and used in every home. It's just a theory, but I bet cases of these things were 'strategically relocated'. As with anything like this, I'm sure most were used up over the years, but it's also just as likely some were just plunked down into the corner of some attic or garage somewhere, and later forgotten about.

They were used by electrician to screw into socket on fuse panels lor light. They were also used in WW2 in vehicle that required lightbulbs tanks, ambulances, mobile field office. I suspect they were also used on ships with large caliber guns to avoid bulb breakage when firing. Check with some on the Battleship museums. If I find mine you can have them. Home Depot has light bulb extenders and so does Lowes.

[@arminwebster1087]

As I sit here and study the picture of the light bulb. It looks like the threaded brass connector is longer that what a normal light bulb would be, and the rubber ring just slides over the base. It is my guess that is was a speciality item made by (whatever company) that was contracted to make them. There maybe some sitting a warehouse (forgotten about) that is owned by the Navy. May you have good weather and following seas.

[@louisvillaescusa]

LEDs burn so cool that it's possible to get LED light bulbs with plastic globes now instead of glass.

[@kensmith5694]

A lot of LED lights have a plastic globe. Glass ones are rare really. The shape isn't quite the same as a 1940s era glass globe. The frosting is also not quite right. If you look at a real light bulb when it is powered off, you will see that the frosting is slightly gray but on an LED it is very white.

[@mfbfreak]

@@kensmith5694 By now - at least on my side of the atlantic - you can also get LEDs that are put in exactly the same shape of bulb as the original incandescents. Frosted but not exactly 100% opaque from the screw base up just like basic quality incandescents, without a plastic bit that hides the power supply. They're neat! But also not terribly common. Most people are satisfied with the conventional ones with the plastic base.

[@kensmith5694]

@@mfbfreak I made my comment about shape after looking at a few options. I could design one where the power supply was in the center of the bulb area and had LEDs all around it to hide it. I suspect that is what they have done. Note for those who don't do electronics: The actual LEDs are very small things. Think of a square about 0.1 inches (2.5mm) on a side. That would be the size of the LED with some housing around it so it can be handled by machines. A central dot about 1/3rd of that size is the part that lights up. On LED makes a fair bit of light but you are going to need something like 20 of them to match the light of a 50W bulb. Each of those LEDs needs about 3V to light it up. To make life easy, you can wire them in series (end to end) so that you need about 60V of DC to make them work. Getting from the 120VAC mains power down to the 60V is fairly easy to do efficiently. The result is a bulb that only gets warm to the touch.

Although many people tell a story of heroic levels of effort to find it, it was in fact and accidental discovery he made after a lot of failure. You used to be able to buy tire patching kits that vulcanized rubber onto the ire you were fixing. You did this outdoors. You clamped the thing over the hole in the tire and put a match to it. There would be a fire and a horrid stink. When the mess cooled off, there was new hard rubber created.

......great video as expected - have you considered making a "DIVE! DIVE!" intro ?

[@ShainAndrews]

6:13 Your solution is to make a mold. Not a difficult task since you have an intact part. You will over mold your new lights with a silicone ring. You can add carbon, and flattening agents to make it appear more rubber like, and not glossy. Durometer is determined by the silicone type. With a little additional work you can make a slightly undersized mold for just the ring. Shouldn't be an issue to slide it over with some alcohol for lubrication.

[@kensmith5694]

I suggested 3D printing. I would suggest for a molded part that polyurethane would be better. You can get it in a color that looks a lot like rubber. You can easily get it up to 80A so it is very like hard rubber. A 1 pound kit will cost something like $40. You just need a dry environment to work in. Humidity can be your enemy.

An option would be latex rubber. Make a mold and add a dye to the latex and you can make all you want cheaply. Note..using LED bulbs heat will not be an issue. Over a decade or so the latex will dry and shrink a bit making your replacement look like an original

[@d.l.harrington4080]

A little something I know from photography darkroom, the red light would washout anything red. You notice that the blue light is over a panel with red switches. It would be hard to see the position of those switches when running red. Just a guess, the blue light would make those switches appear black. I am dying to know if that is a correct assumption. I have to get up to Cleveland sometime and go through the Cod.

Not in this case. Red light maintains night vision but early in the war, when these fixtures were made, the belief was that blue light dilated the pupils.

*The only BLUE I can think of is the two sub personal rotations Blue and Gold.*

[@kotori87gaming89]

Red and blue lights are both suitable for low-light conditions and help your eyes adjust to the dark. Red is slightly better at helping your eyes adjust, but it washes out all the colors and some colors completely disappear. Blue is better at distinguishing colors in those low-light conditions but is slightly slower to adapt. So it's a trade-off: do you need to adapt your eyes faster, or do you need to accurately read charts, drawings, notes, etc.?

[@Name-ot3xw]

Fun thought. Since the lights are attached to the hull, the hull should give off a faint hum in whatever frequency the ship's AC runs at. Wait, is it AC or DC?

[@dfirth224]

Would be DC. Everything runs off batteries. Diesel charges the batteries with DC generator. Propeller motor is DC. Also in case you didn't know, light bulbs last longer on Direct Current. Alternating Current is hard on the filaments. Same was true for vacuum tubes in radios. Cheap radios did not have a power supply. The tube filaments were wired in series like old Christmas tree lights and dropped the voltage with resistance.

[@Name-ot3xw]

@@dfirth224 Likely correct, I'm thinking about it from airplanes. Some are DC but most run AC for the main system. Rectified as needed. E: Big planes. Your Cessna 150 runs off of an alternator and car battery almost exactly like a 40 year old car would.

[@MottyGlix]

@@Name-ot3xw My understanding is that aircraft standard power is 120 volts at 400 hertz AC, and 24 volts DC. When I worked in a lab developing an aircraft system, those were the supply voltages we had to be powered by. (I have some uncertainty about the AC voltage, though. Be aware.) The 400 hertz frequency, by the way, is because many inductive components are frequency-dependent, and with higher frequency the device can be physically smaller and thus of lighter weight.

[@wfoj21]

So - when submerged what is the power source to the bulb? same as Surfaced? Submerged a lower voltage DC should make ships systems "easier" - House light bulbs use 120V 60 HZ AC.

Excellent vid since you have an original blub and mount (which is the hardest part) almost anything can be fabricated or mocked up would just need to find a fabrication place Can we get a video on the other things in that case or the Momsen lung behind you also blue is to preserve night vision

[@paulfarace9595]

All in good time! We're playing the long game!😅

[@dukeofgibbon4043]

Heat shrink tubing might make a good facsimile of the easy change bulb

[@kmoecub]

It would not.

[@danielf7473]

If the light bulbs shattered when a submarine had depth charge explode nearby, wouldn't that also shatter the ones in storage?

[@benjohnson2421]

Would the ones in storage be attached to the hull???

[@fourtyfivefudd]

The ones in storage would be directly attracted to the hull as the bulbs screwed in are. There wouldn’t be as much of an energy transfer to them. Plus the ones in’s forage would have had lots and lots of padding around them. At that point if a blast is big enough to shatter the protected bulbs in storage, chances are there won’t be anybody left alive

where can I get merch with that badass torpedoed skull on it

[@anthonyiannone7618]

every E26 base LED bulb i have ever purchased had a plastic globe

[@paulfarace9595]

There are versions in glass at Home Depot... we bought several hundred.

[@anthonyiannone7618]

Return them and get the plastic ones

[@jordankashuba3467]

😂the HMCS Harry Dewolf ice break doesnt have depth charges. Just a 30mm cannon and coms to call in air support, coulda been a Halifax class frigate though.lol

[@philsmith2444]

Why not mount the light fixtures to the overhead with rubber isolators?

[@matthewmarting7420]

If it's moving multi ton engines off their mounts, as per his ancendote, i don't think a rubber isolator will help

[@kotori87gaming89]

Modern submarine lighting fixtures do use shock-absorbing mounts. The engineering weenies just hadn't figured out a good way to do it yet when Cod was built.

[@mbox314]

Because some big lightbulb company wants a multi million dollar contract to make specialized bulbs and rubber isolators are not expensive enough.

[@philsmith2444]

@@matthewmarting7420 The engines moved because they weren’t isolated. They couldn’t be, though; they’d torque right off the isolators. But simple rubber isolators like you’d get from Grainger or McMaster-Carr, with 2 studs or a stud and threaded insert, would absorb any shock

[@michealfeeney8920]

I can guess what a steam tite fixture actually is from context where you mentioned your holy grail was found, but maybe make a short video on why vapor tight bulb enclosures were important aboard Cod (Hint: What did submariners fear accumulating in the battery compartment???) and in the fleet in general?

[@migda32]

Large heat shrink tubing

[@donaldbrittsan984]

Looks like pipe insulation would be a close enough material.

[@paulfarace9595]

Close enough doesn't cut it on USS COD!!!😂

[@paulfarace9595]

Too thick!😢

BLUE - Blue Sea Systems?

[@NoahSpurrier]

I wonder what lights are used today. Something nearly indestructible with its own backup power is simple now.

[@jaysonlima7196]

When I was in in the very early 2000s it was mostly just 18” fluorescents with incandescent DC backups, and if that went to crap there’s the worlds 4th best bludgeon the battle lantern… nothing fancy

[@dfirth224]

@@jaysonlima7196They now have LED tubes and bulbs to fit existing light fixture.

Have you thought of using bicycle inner tube instead of using hose
