Thanks for the help with the identification - looking a t the cost of them though I may just make the rear section from alloy !

 

that looks like it would have been on George Jetson's car !

 

I’m betting Honest Chucks... Had to be in his accessory catalog. or J.C. Whatnie.

 

I think it's off a boat .

 

I think I found some info on the light ...
I was just looking through one of my old Hot Rod magazines and found this ad in the back pages.
Looks like it could be it...ad says come in different lengths and made by U.S Pioneer.?....
