A set of four (4) replacement switch indicators for 1950's/60's Lionel O-27 Manual Switches. These are extremely durable unike the original brittle plastics used by Lionel.
The surface finish of the Strong and flexible plastics is a bit like a very fine grain sandpaper. It accepts paint easily. I use plastic enamel hobby paints, but acrylics should work fine as well. If you order in colored plastic, please know that they are surface-dyed - similar to paint. So you may need to touch up the spot where they trimmed apart as the base plastic is white.
Simply trim them apart with a nail trimmer or sharp hobby knife, sand and paint if desired. If the fit is a little too snug due to printing residue, the hole might just need to be cleaned out by hand using a 1/8" (I've used a 0.128" drill bit).
The frosted detail plastics yield a far smoother surface but the cost is higher.
