Just wanted to show some pics of a bumper light I bought that is supposedly from a '58 see marking vs readily available lights from the parts store. Forman 68151 about 8.00 each
Same light works in the optional map light bracket too. BD17E519-989A-4082-9DD2-063C665B0AB9.jpeg597408F0-01A7-4914-9850-EEB0112F9D14.jpegF2EAFB72-F324-47AE-92E2-7E8747984696.jpegC282CF8B-5492-4724-B172-9504D053565C.jpeg
Retracs used them also. They are popular because you can just drill a hole and snap them in on most any car.
LL57 marking on 57 Skyliners.
