I really like the proposed rule changes.
For night operations, I'm assuming they're referring to strobes (see:
4−3−23. Use of Aircraft Lights). I think this might present challenges to the average DJI (or comparable) drone owner. I have a set of strobes (brand name withheld to protect the innocent). While I've never tested them at any significant distance, it's my opinion that spotting these from 3 miles is wishful thinking.
If this rule change does come to pass (which it probably will), I think it would be a great idea if the FAA would also set operational standards for strobe makers and the aforementioned 3-mile visibility minimum, therefore taking the guesswork out of the equation for well-intended 107 pilots wanting to retrofit their aircraft. In a practical (unscientific) sense, when you have the strobe in front of you - at arm's length, it certainly appears to be very bright. But when you introduce it into the real world, its brightness, relative to its surroundings, drops off dramatically as the distance between the UAS and your eye increases, not to mention competing light elements from moderate to heavily populated areas.
Just my 2 cents...
