Hey, it goes too good to translate, so it becomes understandable.
This idea, I was inside for other small signals around the railway, but played off the idea when this should be outsourced, for it to be possible.
This is not possible with smaller series, nor in Sweden to make it economically portable.
My idea is to produce an etched sign board as this is very difficult to get into a hobby.
Fiber optics (light guide), I have tried and this looks very good, with just the right glow and giving me a nice glow light (warm white)
I use only fiber optics where there is scope for a better alternative, to depart from the scale.
The advantage is that I do not get any signal that is independent of a lifetime, as it is with an LED or incandescent lamp, the signal with fiber optics will be immortalized.
The other signals I use surface-mounted LEDs with good results in the scales are in semi-zero.
You should see this as a tool to be able to get something in their backyard.
I build up all aspects of signal tables to do before I put in a production plant.
Everything from the smallest scales to zero half 1 / 87, I then present a proposal in the forums, I act in, to see if there is any response.
Send some links to the tests I have done in the railway signals in scale H0 and N scale, you get on that basis make their own assessment, the smallest signals in fiber optics, the larger the surface-mounted LEDs.

Then I spin so on. It all started when I presented the signals of my own train, and this was appreciated, so after the rest is history.
