Let me give you a small lesson in law construction.

Look at the commas in that statement of the law. First, NO Light (so basically, no lights), other then a white light (this modifies the first part of the sentance, So, white light is allowed, all others are not), then, you should remove the small sentance fragment between the commas, then continue reading, so you get, No light, and no revolving, rotating etc white light. So basically, no other color then white is allowed, AND even if you have white, it can't rotate or flash etc...

Then, the other laws are exceptions to the general rule. So, if you are a volunteer FF, then you can have a blue light. If you do construction, you can have yellow, blah blah blah.
