I have a Ho Lima scale carriage which has had lights added. It was quite simply done with an old christmas light and two wires added to each end connected to the the metal wheels sets. Works quite well for me although I don't have a paying public.

I have used it very little as my layout is disassembled but would agree it needs a bit more thought but one can imagine it being done to add a bit of realism (??) to a child's layout. I bought the piece in a jumble sale and will of course fix it up 'properly' before using in on my (future) layout.

Thought I'd add this here in the forum to remind us that this hobby can achieve things simply (and isn't it a pity we tend to loose the child's imagination)....................

P.S. I do go 'whoo whoo' sometimes as I run the locos and am joined in the chorus by my seven year old daughter. This more than makes up for the lack of 'realistic' sound.
