History headlights - help identify

Need some help identifying these headlights, I can't find any maufacturer markings on them. Not even sure if they are car or carriage. Don't remember where I got them, but if I can get the HAMB's help to tell me what they are, I can sell them to fund some needed parts. Thanks.

 

Porch lights from a hardware store ...

 

They look like carriage lamps, originals used candles. Have they been electrified, if so was it done neatly? How do they attach? Bob

 

These are a mystery to me, looks like kerosene or lamp fuel. They could be porch lamps.

 

I had house lamps like that once. On the porch and in the hall on the walls it had like a long "ring" holder you slid the handle into that way you could move them to where you needed.

IIRC, mine had clear glass on 3 sides, so I guess it could have been used on an old carriage being that yours only point in one direction.
