One of the complaints that Consumer Reports or some such had was headlight glare. I was getting flashed occasionally at night, so I lowered mine. Parked 25 feet from the hangar door, put 2 pieces of painter's tape up so that the bottom of the tapes touched the top of the light spots on the door,then lowered each headlight exactly one inch. Wow. I can see better at night (all those photons are on the road instead of out in space) and haven't been flashed once since then. I am a headlight geek and think more about, and spend more on, headlights than I probably should (put E-codes and leveling motors on my '03 Golf, and finally settled on Osram all-weather bulbs.)
Sorry, forgot to measure the height of the tapes before I threw 'em out, but one inch lower than they were from the factory.
If it's not foggy
and your foglights are on
you are a doofus.
