Cuda Fog Lights

Also have this over in the WIW forum.

A friend has offered to sell me four of the G.E. # 4415 fog light lamps, the ones that have the word "FOG" cast into the lens. Two are period date coded, and two are still in their original boxes, circa 1980.
Was told to "pay me what you think they are worth". Any thoughts as to fair value?

just a guess on my part because they are not real hard to find

$60 for the 4

Thanks Bill.
