I’ve been collecting items for my garage and lights seem to have had the biggest impact when the door goes up .
Today I came across & bought a couple more lights but I’m not sure what genre of transportation they’re associated with.
There were three, two with red lenses (which I bought) and a blue lens.
The guy selling them said he thought the Railroad was the only ones using blue lights.
I’d planned to paint them transportation yellow & weld up a mounting bracket but thought I’d ask around & do some research first.
The Forum has always amazed me with the combined knowledge do I figured I’d start here.

Anyone seen this type of light before?
For size reference they’re 12”x 12” with a 9” glass









?????

Its been a long time since I saw them, but I think the LORAN guidance system on the Ohio River uses similar lights.

This is all I’ve found of blue lights associated with the Railroad.
Though none of the images look anything like the lights I bought as mine doesn’t even have a way to attach the typical RR light hood.
I’ve yet to find anything other than red, green & white associated with the water.

Neat place with a lot of cool stuff.

I’ve never seen or heard of a blue light I’m Maritime use. Red, Green, White, Amber.

This is the only maritime use I’ve found & it’s from Australia. Nothing from the US.
I like a good hunt & search mystery. But even with the railroad direction none of those lights look like mine. So I’m still searching the webs.

The US does not use blue in maritime lighting. Not in traffic direction or channel marking or ship marking.

White
Yellow
Green
Red


I don’t know Jack about trains.

Looks like these may very well be Railroad equipment. But I’d really like to find a pic of these in a railroad photo. I’m not a Railroad guy myself.

I may not know what the lights are for but I will stand my ground and insist, "THERE ARE FOUR LIGHTS!!!"

(Sorry, I couldn't help myself. I need entertainment and there's only me to provide it.)

Measure the lenses.

See if the glass has any numbers on it.

MS24489 is the number for a red lens for airport lights. The lens would be around 8 3/8 in diameter.

I’ve been railroading for 14 years and have never seen anything like those on the rails. My current property has a lot of really old Missouri Pacific and ATSF hardware and none of it looks even remotely similar. Let me ask around though. As you note RR lights typically have the hoods on them.

These don’t look like they would have been wayside signals, possibly something in a shop setting. Blue signals are what we use to lock out tracks when mechanics are working on equipment in them. Red, yellow, and green are what railroads use for signal indications on wayside signals.

Go Google “railroad dwarf signal”, these share a lot of similarities with them, save for the points to attach a hood.

Don't airports use blue lights to identify the taxiways? Could they be aviation related instead?

^^^ yes, that’s where I’ve seen blue lights…and on top of police cars..but that’s another discussion

Some pics of the decals & markings.
