ehh. just stick some 3M reflective tape on the side of your bike if you're worried about that.

having to turn each individual light on and off by hand is an additional burden that sounds more hassle than its worth.

if you have two spoke lights on each wheel, that would be four separate buttons you have to press just to get the side lights all turned on. plus two more buttons for your head and rear tail lights. that sounds like a headache. you'll go crazy pressing all those buttons.
