They should be better, as they are full cut-off fixtures, so if you  
are above them, or at a distance horizontally, insects won't even see  
them.

To an impressive display of  just how well they work, if you stay in  
the right lane while crossing the new bridge from Dartmouth to Halifax  
at night, look down on the end of Barrington Street. The roadway  
appears lit as if by magic.
