Relevant to using red lights at night...

Although I once read a long technical essay on why red light is preferable at 
night, during my time in the Merchant Marine most of the night lighting was a 
very dim white, almost always with a dimmer on it.   As time went on there was 
more of a move away from red lighting and toward dim white lighting..  I heard 
that the Navy has done the same.

Many things are easier to read in white lights rather than red.

I also have been confused on occasion by colored lights on a boat that were not 
navigation lights.  White lights generally mean "do not run me down" whereas 
colored light show what direction the boat is headed so a case might be made 
that extraneous white lights would be safer.
