Clear plastic rods (light guide)

RS do clear plastic rod from 6mm diameter.

================================== You could try clear plastic knitting needles. They're readily available in a variety of sizes and should be cheap enough to experiment with. You might be able to bend by heating in a pressure cooker as we did with pipe stems.

Is this for a specific requirement ?

i.e. do you have precise dimensions?

some CH pcbs use them, else I could possibly turn something on the lathe

Farnell in Leeds carry an extensive range of light guides, pipes, splitters etc

I might have seen something like this in B&Q, but might be dreaming. They certainly do various sizes in white plastic.

Perspex was the traditional material for light guides before fibre optics. It has a high level of internal reflection, so, unless you make the bends too sharp, you get very little loss even in quite long runs. However, that also means that the light is very directional when it emerges, so you need to dome and roughen the end if you want anything but the narrowest viewing angle. Perspex rod should be fairly easy to get hold of and it does bend with gentle heat.

A pack of 100 that may suit - 7 quid delivered.

Are there any 'shows', sunday markets, car boot sales, near you, i.e stalls selling overpriced tat, usually including fibre-optic lamps for a pound or two. A couple of the fibres and a touch of superglue to bundle them together is all you need.

But at that price - 7 quid for a hundred precut-delivered free, ...

Dealextreme has way too much stuff though.

boxes. Ordered what seemed like a huge number of things and it only came to about £40...
