I don't think that the headlights are too weak but it does take some time to get familiar with the "cutoff" that projector lenses have. Some have done the H9 bulb upgrade and a lot of people have done HID upgrades to improve performance. Your headlights may just need to be adjusted a little.
Yeah, the 06+ headlights are really not bad. 03-05 stock headlights however, are a completely different story, I could not stand them and replaced with nice HID projectors before I even got the plates and registration for the truck.
My 2007 Limited has great lights. So much in fact that I put some light tinting over them to add a little attitude to the ride. You can see it a bit in my signature pic.
