These two headlights have the bulb focusing adjustment screw located in two different locations. Is this due simply two different suppliers or characteristic of different years?
Bottom one is for 15-16 and possible for 17. Usually found with magneto lighting. Top one for 18-25.
Makes sense. The top one is from my '23 runabout. The bottom one I bought at a swap meet on Sunday with some other parts. If that's the case ... anyone need the earlier one?
The socket in the top photo is the socket that goes in the '15-'17 light in the bottom photo.
It will work the way it is with the straight headlight plugs, but the later style socket will NOT work with the right angle headlight plugs. The right angle will end up pointing sideways.
: ^ )
I'm reinstalling my headlights, is there a right and a left side or are they both the same?
There aren't left and right on the '25 and earlier, the '26 fender mount headlamp is left and right style.
Also, the earlier head lamp with adj. screw above the socket also has the square shoulder mounting post. That shoulder only fits the earlier fender bracket with the single flat on the inboard side.
Earlier post on the right, the later post is tapered sided, fits the later fender bracket with the twin taper side.
The earlier post won't interchange with the later fender bracket.
Thanks Keith .. I'll have to look at all my sockets and focus adjusters to make sure I have the right ones.
With the bulbs available today, the 18 to 25 position will not have a dim and bright (low/high) but a left right shift. Several of us in my area have moved the focus hole and sleeve to the 15 position to have a true high/low shift from the bulbs we can get today.
That adjustment screw has to be totally horizontal from the socket to have the light beam show horizontal on the wall, like the Ford Manual shows.
The second photo would also be correct for an early 1926 Ford Driver's side Headlight or the ones without the fender to fender bar.
A friend told me that his 1920 head lights do not have that screw at all, but the socket can be slid in and out for focus.
The reflector has a small bulb near the top and the Dim position lights that bulb.
The main headlight bulb only has one filament that is lit when Bright is selected.
Some Model As had this arrangement, but his headlight is an otherwise correct Model T light.
Does anyone else have that type of a headlight?
Those are typical '19-'20 lamps on the first Fords with electric start. Mostly seen on sedans as they got electric first.
The double bulb don't have adj. screw.
Thanks Dan for solving that mystery!
