I 100% agree. I expected my Tridiums to provide more light than they do. As others have said, they are mounted too low for long distance illumination. They light up the spot right under the bike and forward about 10-15 feet before merging with the illuminated area of the road from the headlamps.
I do leave my fogs on 100% of the time to increase my visibility. I had my wife drive in front of me and she said it was very bright (the lights, not me). I have seen a few cagers creep out and then stop. No idea if this was a direct result of the increased visibility of the Tridiums.
