Re: EF lights...
On EF/EL Fords there is a difference between highbeam operation on base models and Fairmonts. The Falcons have two single filament globes in each headlight. The low beam, which is the outer one, and the high beam being the inner one. When you flick the high beams on the low beam globe continues to get power and the high beam globe comes on with it.
On the Fairmonts and Fairlanes/LTDs there are one twin filament globe and one single filament globe in each headlight. The twin filament globe is the outer one, the single filament globe the inner. When low beams are on one filament in the outer globes is working. When you flick to high beams, the outer globe switches to the other filament(both aren't on) and the inner globe comes on also. So the outer light is your high beam and the inner has more of a driving light beam to it.
