Thorshammer, I picked up those lights too, but they're impossible to aim. The plastic teeth on the mounting bracket only allow you to rotate them at roughly 10 degree intervals, which for me means pointing at the ground in front of the jeep, or at the treetops. There's no way to do any kind adjustment in the middle, much less fine adjustments.
I do really like those lights, as they throw a very narrow, very powerful beam. But if I can't put that beam where I want to, they're useless to me.
