Identify these lights? Arrow lens ?

Here are some lights that came out of my grandpa's place years ago. Unfortunately a s****py got the mates last summer, and missed these two. I'd like to get them in the hands of someone who can use them...

My guess is its one front and one rear, maybe aftermarket?







Regardless, they are some cool old lights.

 

I think those are a set of stock turn signal indicators from a pre 39 Ford big truck. Possibly as old as a 28, I don't think they are aftermarket.

 

My dad thought from a 30s truck, but couldn't remember what.

They are aftermarket. Generally used on trucks and buses.

NOT uncommon, back in the day.
