Got a question for those of you who are familiar with the lightbulb trick as it relates to the DCS signal and consistency of track power in general. I'm planning a new layout with a number of sidings. Barry's DCS Companion Guide strongly recommends placing each siding in a block with a lighted bumper and SPST toggle switch. The toggle switch is there to reduce power consumption when there is lighted rolling stock on the track, and to also prevent needless power-on time on command-control engines. The lighted bumper is there to help keep consistent track power and hopefully maintain a DCS signal strength as close to 10 as possible.
I'm wondering... if I went with a lighted SPST toggle switch (maybe like this: click here), would that kill two birds with one stone such that I may not need a lighted bumper? I can't think of why not, but I figured I'd ask the braintrust first.
