Please note that this model was originally created for the material: Clear Ultra Fine Detail Plastic, so therefore there are models of lenses in the model.

This is my take on PRR USA 4102 Dwarf Signal, Standard S-410-D, please use 0402 SMD LED´s in this signal.
I hope the signal will look good for it is made from photos and some drawings.
I recommend a pipe/tube whit an OD on 1.677mm.
The tube is K&S Engineering #1008 ø1/16"(1.57mm) 0.014"(0.355mm)

This signal will need a 3mm (1⁄8 0.125") hole in the "gound".

If something is wrong with this model, let me known!
