Concerning the bulbs, I recommend using LEDs in the 022 switches. Doing so eliminates melting the lanterns, which often happened when I used incandescent bulbs.
One reason I stayed with tubular track is the O22 switches. They may not be that realistic looking, but I think they have a charming appearance and my experience with them is that they are affordable in good operating order on the used market, reliable and relatively easy to fix if anything goes wrong.
I started out with 027 tubular and decided to use O Gauge when building my last and current layout around 1995. I much prefer 022 switches with their voltage plug drawing power from the transformer as opposed to the remote control 027 switches that draw power from the track, though I know they can be modified to also draw power from the transformer.
