It would be neat to have either:
1. Entity filter list setting, with either whitelisted or blacklisted power pole names, for inbuilt light selectivity.
or
2. Power Poles Lighted Wire Reach Threshold: Generating a blacklist for poles under a certain wire reach, so only the more advanced/larger ones get the lighting feature automatically.
With mods that add other types of poles, the first setting in particular would be a nice addition so that e.g. a basic wooden pole could be lightless, while a slight upgrade to a metal pole would be fancier.
