Picked up this light last weekend, has that over engineered military look to it. Lense is 2 5/8 diameter, case is cast aluminum 3 1/8x 2 5/8. Would make a nice under dash light.
No markings on it other than a 53 10 7 that is up by to top contack points. the 10 is under the contact. How does one look at a socket and know the voltage? Maybe a view of the back will help.
Bob, unless it's an interior light of some kind, I would doubt that it's aircraft (looks like it'd stick out in the wind a bit too much for a plane)... maybe from a boat?
I think it is an interior light, the lense rim turns 360 degrees and makes contact with the bulb and wire connector, so I think this is the on off switch. Remember swapping light bulbs is the top of my electrical abilities. That volt question was way over my head.
Any markings on the bulb itself? some industrial bulbs will have voltage markings on the bulb itself. Pull the bulb and look it over carefully.
probably not wwii or aircraft and likely not military either, if it were aircraft it would have an option of sorts for a red lens....to preserve night vision. it may be from some sort of ground equipment. i.e. inside a search light generator to see the engine (which by the way used a 6 volt battery as did most light trucks of world war 2) but, who knows?...So what you're left with is a cool old light, wire it up and run it. forget what it used to be....make it about what it is now.
so what you have is if I'm understanding right is a lamp with bayonet mounts much or like a brake light bulb. If so take it to parts house and find a bulb that fits and give it the proper voltage. the lamp itself is not going to care if its 6,12 or 24 volts. And it probably is a van or rv item.
----------------------- No - NOT from a van or RV. Methinks - DEFINITELY - a 'daytime running light' for a '35 Henway "Model X" 'long-wheelbase business sedan' or an equally rare, "Model Y" '9-p***enger, close-coupled coupe'. These unique 'daytime running lights' were part of an alleged, but highly ill-conceived and short-lived, factory "Safety Package" option that was available on these cars for the 1935 model-year only. Their 'one-year only' option status was due, mainly to the fact that, due to dealer malfeasance and chicanery, the 'daytime running light' package was usually only able to be ordered in conjunction with Henway's infamously deadly, tragically ill-fated and mercifully also, 'one-year-only' 'ACME rocket-powered ejection seat' option! It's hard to put a precise "money" value on it, as these ultra-rare 'daytime running lights' are now so highly coveted by the Henway collector community, as to be considered virtually priceless. But I'm sure that just about any collector, restorer or hot-rodder who owns a 1935 Henway - with or without the factory-installed 'ACME ejection-seat' option even - would gladly and happily give you his left nut, his wife and first-born child and *possibly even* his used chewing gum or string collection to own it!!!

Almost all apart, still have to soak it to free the inner ring. The guy I bought it from said it was a Mustang backup light "Just like" the one in the movie "Gone in 60 Seconds" I knew that was BS and bought it. It has to be a Military item, just too make well made pieces.
try looking for a pic of one of those "Flexiable Flyer" buses from the 40's early 50's - think the White Motor Co made them....just saying....
Doesn't look like anything military (either the flying or creeping across the ground variety of hardware). As noted earlier, almost all the the interior lights (and this thing doesn't look at all like an external application) have options for red lenses. All the old "map lights" and such I have seen/used are a bit sturdier (over engineered), have variable power switches (low, med, hi) and have that patented military coating of CARC paint. Still, you have a cool little bit of kit with a nifty looking "fluted" lens, and it looks like it would fit beautifully in some nook under a dashboard. Wire that puppy up and enjoy!
Whoever mentioned that it might be a reading lamp for a greyhound bus is definitely barking(no pun intended) up the right tree in my opinion.
