fiber optic lighting ?

I am thinking of using fiber optic lighting on a new build, has anyone used these, I have been using grain bulbs but when you have many lights say on a mast is hard to hide the wires. What size wire to use, if the end is colored say a clear red will it show or should I use colored wires?

You'll only get light straight out the end of the fiber... is that what you need on a mast? I understand they're great for, say, portholes on an ocean liner...

Yes as Pat said ..

I offered a question a while back ..that if the filiment was stuck into a goob of hot glue..allowed to cool would it illiminate the goob of hardened glue ..Got some great feed back ..but nothing as clear as mud ..

Saying that ..Im thinking if that worked could use some silicone to make a mould ..and just put the filiment in and squeeze in some hot glue behind it ..

All sounds good on paper

Pat didn't think of that but wouldn't it reflect inside the clear lamp housing?

Not much, likely... hard to beat an incandescent, just as hard to run those wires!
Using bell wire might help, as well as using a brass mast for a common ground. Did something like that here:

I tried fiber optics and it's great for very small lights like maybe wall lights over the deck. You can melt the ends of the FO strands and get a little bigger light but mostly the strands are so small they don't put out much light at all. LED's and grain of wheat bulbs are probably the best things to use with LED's being the best in my opinion. Pete

I use F.O. quite often on sci fi models. The colour is dictated by the light source. Quince.

Have fun, but GOR incandescents are still smaller and more omnidirectional...

And more power consuming.

Pat is right ...and Olscuzbut your right ...

The happy medium for me at least is that the Led can easily be run in series without to big a worry of excess wiring..They are cheap ,readily available and with the right resistor for 10,000 hrs +/-..

Ive always had this fear of a busting filament in a GOW bulb, especially in an area hard to service ..which is everywhere on a model ship ...not so much to worry with the Led ..

Dollhouse wire is multi strand 2 conductor and made for small bulbs. Turn the mast then place it on your tablesaw and adjust the blade heigth to the radius of the mast and rip a groove the length of the mast. Place the wiring in the grove and fill over the top of it. You can pigtail out at the required levels for each lamp. I use testors plastic model filler to seal the mast groove.

The disadvantage of fibre optic is that it doesn't like corners. The light only goes round gentle curves.

Wiring for leds, lighting, and other low powered add-ons. If you have ever dismantled an old computer, you will find quite a few ribbon cables inside connecting the different components. Cut the connectors off and tear off as many conductors as you need. Keeps your wiring neat and can be glued to the inside of the hull or upper structure.

There are a lot of good suggestions here. I have used fiber optics on models, my modified Robbe Neptune uses them for the deck light and the spot lights. 2 bulbs 1 clear (6 spot lights) and 1 amber (10 deck lights). Now I have gone over almost completely to LEDs. There are 44 LEDs in my Calypso, If I had used Lamps it would kill the 4 ah battery in less then 1 hour. That's just lights, with motors and radio I would have about 15 minutes run time. As it stands I get over 2.5 hours!
