Clearance posts with lamps were placed at fouling points of sidings and loops and were painted white for visibility. The lamps were lit at night usually by the Station Assistant and spares would have been kept along with kerosene in the lamp room attached to the men’s toilet.
I have made these in two material types, the White Strong and Flexible for those who may be worried about the posts breaking if hit while cleaning track with a track rubber and Frosted Detail and Frosted Ultra Detail for those who want more detail and who also may wish to have the lamp lit.
If printed in Frosted Detail or Frosted Ultra Detail material they may break if knocked hard (I don't know yet as I have only just installed one), if so then just pull them out and replace with a new one.
These clearance posts with lamps are to be mounted in a 3mm hole drilled through the baseboard at the clearance location of a set of points (turnouts).
The Frosted Detail and Frosted Ultra Detail are an acrylic material which can transmit the light from a 3mm golden white LED placed into their mounting hole from below the baseboard.

I have tested it with a torch from below and it gives a small circle of light that would only be seen with the room lights off as you would expect, this is no glaring headlight.
