Okay, the LED oil lamps light up as expected, but it turns out that in the dark, there is lots of bleeding light from the actual body. I think that next time, and before I fit them fast for sure, I will repaint the lamps. It would help with the delicate bits of trying to make it look like there is an iron on them as well. The single 1.5mm hole worked well, as opposed to the two .8mm holes suggested in the article.

And a question. Nigel Burkin's book refers to shuffling CV values to get the lamps to stay on regardless of direction selected. Can I just solder in the wire that feeds the reverse direction lights into the circuit I've got to avoid that? Although I would, presumably still get the dwell between directions I get sometimes.

Anyway, this has been so much fun, I'm going to determine a specific use for a loco and light it accordingly. Tail lamps too. At £3.50 a go, less VAT, the lamps are well worth it for the extra play. Just got to finish a layout now.

Next project, probably to be started before this one is finished, is fitting running and interior lights to my 156. This is where my robotically qualified friend will come in. All will win. His son and my children will watch a film. Our wives can talk about babies and kittens or whatever, and we can work out a circuit to do what I want.

I feel my humble Austerity may need a lamp or two. Didn't they go in for a red and a white on each of front and back? That would look good.
