Looking to ID/ locate bulb.

[rcl700]

I have a set of fog lamps on 1948 ply. 

The bulb reads 4 5/8 . I'm looking for replacements. I provided power but they did not light up.

 

6v pos ground car.

I cannot help a lot but I am thinking that the 4 5/8 is the bulb diameter as I believe there was a 5" and a 6" option during production. AB only sells the total unit that I can see but you may be able to phone them and either get a bulb from them or source a supplier that may have one to fit.  Dave

I do see a bulb behind the lens that has the front of it with black paint.  Question, since thee isa bulb can the outer trim ring be removed to expose the inner parts of the foglight.

 

Suggestion see if you can remove the outer trim ring and remove the lens and then see if the bulb can be removed. If the bulb can be removed then I would think it is just burned out bulbs. Find the bulb number and it just might be a single contact bulb and then do a search for the replacement bulb.

Correct, it is a sealed beam bulb. I'm just having trouble locating amber 4 5/8' 6v sealed beam bulb replacements

did you remove the bulb to see if you can find the number that is usually on the backside of the bulb....the 4 5/8 is typical to Guide and often even can be located at tractor supply for a clear driving light or red for stop....yellow not so common at the tractor places.

If these were mine and, of course, unless the OEM replacements are readily available, I would try to carefully grind-off the back to make it into a DIY removable-bulb. If you manage to get a good-quality hole cut, you should be able to fit a standard bulb socket of your choice in there  

An alternative would be to get a modern light of the same size/shape with the bulb, and attempt to swap just the front lens (glass) portion from the original lamps.

 

Also, if you have not already done so, take the bulbs out and check your lamp contacts. It is somewhat unusual that both of them are bad 🙃

They do come apart.  I had to use a Dremel to cut the ring that holds the amber lense in place.  The back is metal with a gasket and clamp holding the lense in place.  The bulb is soldered in.  It's easy to de solder and remove.  Carful with how much heat you use.  I damaged the mirror finish on the first one I tried.  Don't know where the fog light bulb is - I'm moving to the new shop and it's packed away somewhere.  I have some extra replacement bulbs I could send to you if you can't find them.  The bulbs I have are 32 CP intended as head lights but they can be modified to use in a fog light if you want to keep your original lense.

 

New fog light bulbs are available but the ones I have are stamped with Mopar and I wanted to keep that.

If I recall correctly, sealed beam bulbs are typically identified by "PAR" for "parabolic aluminized reflector) and then a number which is the bulb outer diameter in 8ths of an inch. So a sealed beam replacement would be a 6v PAR36.

 

But that is all from memory and my memory is not what it used to be.

 

And it looks like that is not really a sealed beam setup but rather a bulb and reflector.

This is a sealed beam. I have no continuity between power and  ground on the bulb

You were part of this, all along 😋

That's unfortunate... I would try to retrofit these with a standard bulb, or re-use the front lens. You've got nothing to lose, it's already broken...

from the image I saw of the rust and corrosion it is no surprise that you are experiencing issue with voltage and grounds.
