curious on a hole
 

My early 28 and a friend's 29 has a small hole in the dashboard over on the right face.

I have used this for my blinker 3 way toggle switch now.

If I recall, OZ laws many moons ago required a minimum of a single tail light burning while parked on a public street at night.

I am curious as to whether this hole was a general spot to put a small switch to follow this law, as the the early cars had no park lights.

Probably totally barking up the wrong tree with this one.

My 28 Phaeton and early 29 Tudor have fluted headlights, which have one parking filament and one headlight filament in each headlight. No bright/dim on the 1928-early 29 Model A's, but they do have parking bulbs, 2 in headlights, and 1 in tail light.

Some people change the headlight bulbs from parking to a bright/dim bulb. Then you'd loose the parking filament.

Oddly enough my 31 Tudor has a hole on the right side as well, previous owner had put in an adjustable vacuum switch for the passenger side wiper motor. It looks like it belongs there.

Did not know that Tom.

I have never heard or seen a dual filament headlight bulb, which has a headlight and park light filament side by side.

I thought the bright and dim on the wiring diagram meant high and low beam.

If, which is it probably is not, hole is for an old OZ law, one would think a separate or modified circuit would have to be installed, to just turn on tail light on its own.

Otherwise, the feed would travel back thru wiring and light headlights and the battery would not last long.

No diodes in 1928.
