Must have been a popular, simple modification.

 

It gives the truck kind of a sleepy/lazy just woke up look

 

John,
You're right! That's exactly what I was going to say!

 

Na, it gives it the right amount of attitude, Like it just don't care.

 

Bedroom eyes are kind of sexy

 

Looks like about 1955. Here are some on eBay for $19.99 not chrome though.

Unpainted it looks like a cover from a 55 or 56 Ford sedan would work as well.

 

I think they look very, very cool on the 52 grill, it ads so much personality. To me it kinda looks as if the truck is blinking, tired, or maybe like its in the mood to meet another 52 nose to nose.

 

These were very common on 49-54 Ford cars back in the early 60's. They were a cheap, (probably) 6 dollars or so, add on that gave the appearance of bringing the car into the "Frenched in" headlight era of the mid and late 50's.
Finding them on a pickup doesn't surprise me at all.

 

mine were in a box in the floorboard, along with the hood ornament.

 

Are they the Jeffrey Allen Visors? I see them on E-Bay.

Not 1955 or 1956 Ford car. The member in post 24 identified them correctly, there from J.C. Whitney.

 

The old style, the whole trim ring including the visor, are much more rare and probably valuable, than the newer one size fits all type. But, the advantage the newer ones have is that one does not need to match the mounting screw holes. They just get sandwhiched between the headlight and the trim ring.
