Theatre lights

Many thanks to the person who answered my question, but I meant one can buy very small square displays with number lights in them, eg 1-9. That is for the numbered platforms. They are before the station to show the driver which platform he is going on. They are aroung but I cannot find any. Thanks.

Erm, why have you started a completely new thread?

Also, if your name is Chris Smith, which I think it is looking at the style of your post, then I have already given you an answer to this question on the MT forums!

Perhaps you would care to share the answer HERE for the benefit of other modellers who DON'T frequent the MT fora.

You'll have great fun building one yourself! You'll need a small 7-segment display usually available from Rapids/Maplins etc, but I don't think they are white/yellow, mainly green or red which is a bit of a problem.

There is a book by Roger Amos entitled 'Wiring a layout' (I think), and this has some details on building your own theatre boxes.

If you don't feel like building your own (probably a good choice) Roger Murray does a good range of signals including a theatre box available at £22.

Thanks for that. As you say SMALL 7 segment displays tend to be green or red. However, if you run a green one at or near it's rated current, it is quite bright. Place a sheet of yellow acetate in front of the 7 segment green display and it looks a yellowish colour.
Alternatively, have a dig in the attic/cellar for a 1970's LED calculator with a green or yellow display, Commodore I believe did a green one.
