American PreFocus Bulb needed for my driving lamps. The fog lamps were made app. 1955- 1960. I able to find the same bulb made for headlamps except those have two contacts for a double filament and mine has one contact.
Any help would be appreciated.

 

The old LUCAS numbers you might look for are 185 or 685 and 323 - all are 48 watt with the fillament 'shape' being the differance.

Moss uses their own numbering system so you have to dig deep but they may be the best place to look unless you have a local shop that specializes in things like old Jaguars ...

 

... and then there's this guy :
