Phak1 I find that 2 12 volt woods junkyard 1$ headlamps ,that are made to shine right on the white line on dim work about as well as anything on AD trucks. On bright they light well down the road so hopefully you can see the multitude deer population we have here. As an old geezer I like to know where the white line is when I meet those new halogen 5 mile lights that they wont dim !! Maybe it's LED's anyway too bright !!
