[Paddlewise] PFD lights - flashing red or continuous white

I just bought a PFD light and it comes with two led bulbs.  Ones a 
continuous white light and the other is a flashing red light.  What are the 
regulations (Can &USA) regarding lights.  I thought a continuous white was 
illegal on a PFD.  Both are unidirectional.  IMO the white seems much 
brighter and I believe would be easier to see in stormy seas, but I could 
be wrong.  Is there anyone who's had real experience trying to spot these 
lights in the water at night?
