10-4 on the 'out of adjustment', many drivers, talking 4-wheelers in particular here, do not realize it takes just a few turns of the proper screw driver to adjust. Many are too dim as well or pointed to low.
i believe any bulb that has a 'DOT' approval number stamped on it is legal. One thing to consider is, if you go over 65 watts, it may tax or over drain your charging/wiring to the point of melting wires or blowing fuses, i googled this info up as there is lots of good info out there. You can get kits to upgrade to 'high density' lights but this is a whole new ball game. When you pass a vehicle with HD's on the road and they forget to dim the brights, you definitely know it.
i always remember what a dude used to say that i worked with who taught defensive driving, 'don't flash on your brights to signal someone w/ brights on, because when you do, you then have two blind drivers coming at each other x( ', better to look down at the white line at the shoulder and save your retinas, among other things.

Sit beside me, my only son,
Take your time... Don't live too fast,
Troubles will come and they will pass.
And don't forget son,
There is someone up above."
