Methods and tips for aiming headlights

[Stg2Suby]

Lots of talk about headlights lately and I'm wondering what methods folks are using for aiming?

One way is the measuring method ie: vehicle 25' back from a wall on flat ground, measure height to beam just in front of front bumper, height to beam against wall should be X inches lower.

The other way probably more common is the subjective trial and error method on a dark road until if seems right.

Any tips tricks or suggestions??

Usually against a wall. I use the wall so I know they are both at the same height. Drive to work or home and adjust again if needed. I can tell right away going down the road if they are too low and sometimes too high. If I get flashed then I know they are too high. Also shouldnt get flashed when the truck is loaded.

I would agree the majority of folks are clueless regarding proper headlight aim, I think one issue is the low beam pattern is pretty broad and can still provide OK lighting when aimed way too high so people don't realize there's a problem. I'm just getting my 09 Dmax lights dialed in after having it levelled and installing a deck and airbags; the adjuster is quite sensitive each 1/4 turn seems to make a big difference.

Yeah for sure getting flashed when you're on low beams is a strong indicator you have a problem. That said I had my lights set a bit too high for a long time and I never got flashed at all.

Funny that every cheap ass rental car in France had cockpit adjustable headlights but they can't seem to engineer a system here for a $50,000.00 pickup that is expected to carry cargo in the back.
