Indeed, little things you attached to the window ( they clipped over the
edge and stuck out). Single bulb in an egg shaped plastic lens, red one

to go over the window.

Not that I’m old enough to have used one but I remember my father using
them and fitting a little 2 pin connector to plug them into in his cars.

As I said last time you mentioned this, this is a DIY group, so
in addition to the Woolworth's socket, you shouldn't leave out
the mention of making your own parking light from a bit of bent
tin can, a fish paste jar, a bulb holder and a red sweet wrapper.
