I know how to adjust my headlight, but how do I know that's it's aim'd properly?

 

take it to the dealership and let them do it. i had them do mine for 10 bux the other day

 

Nice, thanks!

 

do it for free and save urself some gas and 10 bux...its not that hard..there's a screw behind the headlight..park infront of ur garage or by a building without texture or lines and adjust them from there...i had to re-adjust mine when i lowered my car and it took no lie, 2 minutes in my garage..

 

Nice, thanks!

 

iirc in the owner book or on the DIY section here is the factory specs for setting the light height

the mark on the lens is a measure point- and you mark a height on the wall for max intensity part of beam to be at point X at Y feet away

Remember the right -passenger side should extend out farther to help see the white road edge (fog) lines, and those pesky pedestrians and bicycles out after dark with no lights
The left beam needs to be down and in slightly to keep from blinding oncoming traffic and causing them to crash into you!
You wont believe how bright our lights are until another TL follows you thru the mountains at night---constantly flashing light into your mirrors- its worse coming at them!
So be nice to other drivers and keep the beam in and down where its supposed to be

You can also look up online for specs and tips-
like use a + scredriver as a cam gear to move the adjuster gear, just follow the V shaped on the plastic right to where it needs to be, maybe tilt tool rearward slightly for better access
