Loco Lamps when shunting

[Mike 84C]

I seem to remember a post about the colour of loco lamps when shunting. My 1933 GSR rule book says Rule 123; Engines employed exclusively in shunting at station yards and sidings must, after sunset or during for or falling snow,carry head and tail lamps both showing a red light or such other light as may be prescribed. So maybe not a red and white over each buffer as on BR. Sorry if you all knew this already!

The old oil headlamps had a red filter glass inside, you could swivel the top to turn them from white to red, that is if the glass wasn't broken.

1967 CIE Rule 123: Engines employed exclusively in shunting at stations and yards must, after sunset or during fog or falling snow, carry one red and one white light, at the front and rear, one over each buffer.
