curious on a hole

[pooch]

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.
