Love to ride at night and in North Carolina, deer are a constant thing on my mind. I do slow down drastically, and have had a close call with not just deer, dogs, cats, possums (they will actually not move even if you stop). I have noticed that the 2004 light does not shine out as far as my 2003 did. I have adjusted the light every way possible but nothing seems to work, so I run my high beam all the time, and just hug the outside line when a cage is coming at me. If the light is to bright for them ol well, they have 2 lights, I have only one.
