Are you talking about angling them down a little? The ability to do it from the cab with a thumb switch near the left knee came out in the 2010 Tundra. There are mechanical adjusters around the headlights in earlier versions. I've seen the 05' Tundra and the 07' and later Tundra's. What year is your Tundra?
That first pic doesn't have any written instructions for it, and that adjustment is done using a phillips screwdriver which only shows the shaft & not the handle. If you follow those adjustment steps you shouldn't have anybody blinking their lights in your face because you're blinding them. Good luck
