Thanks for the positive replies to my turntable.

I want to have a inspection pit in one of the loco sheds, but this needs some lights.
I had the idea to place a optic fiber along the top and two Led's outside shining into the
optic fiber.
Well that was not very effective.
So I placed six Led's in series last night and this will work much better.
Will do another row of Led's tonight on the other side.
Once fitted I can still play around with resistors to dim it down a bit.
