This is an NOS  driving or fog light assembly which was factory optional on 1952 and 1953 Mercurys.  The chrome housing fits the LH (driver’s side).  It includes the NOS GE “FOG” light bulb and bulb “bucket” assembly which is adjusted for up and down and right and left  front the adjusters located in the front of the chrome housing. The bulb “bucket” will fit either side. Also included is the factory cloth covered power wire with bullet connector. The chrome housing shows some shelf wear which you can see in the pictures. We charge actual shipping only and are always glad to combine shipping on several auctions or you would be welcome to pick them up at our shop. Thanks!
