This is a pair of New Old Stock Accessory Lights
Manufactured by Custom Accessories, Part number 93338
They are brand new, never installed.
They are also 20+ years old, so there will be some scratches in the chrome, guaranteed.
They're equipped with a 12v either single or double contact bayonnet type incandescent lamp,
similar to what you see in landscape lighting. I don't know if the included lamps are still good.
There are some pretty nice LED replacements out there, if you want a little more punch or better color- 
I think what's in there might be around 15-20 watts.
To be clear, this is not Halogen, Zenon, HID, or LED- it is incandescent, just good ol' fashioned light bulb
like you'd see in Gramma's refrigerator.
Would be cool for some ambient lighting on a vintage camping rig, or maybe on a boat,
maybe around the awning on a classic RV?
Would not be cool for a driving light, or anything you'd want to be super bright. 
No returns on this item- best to get all your questions in before you buy.
