A model railway light show

[McColm]

The  Epping-Ongar Railway is putting exterior lights on a steam engine and carriages this winter on a stretch of track that used to belong to the London Underground. Tickets are £20.
I was thinking could this be copied on a 00/ho scale,  the larger scales would be better. Lightning inside a carriage has been available for quite some time but to have it on the outside. I have never seen this done before and are there bulbs that small or LEDs?

There are LEDs which are pretty tiny, they come mounted on an etched strip and you can cut them off to length.

Thanks Kit.
