I've noticed newer Toyota headlights's are really bright and angled too high up. That or Toyota drivers leave their brights on more.

It's funny you say this, because I got a lot of flak on Reddit for saying the same thing.

You can see this effect clear as day when it's foggy - every other vehicle with projector headlights are aimed down, at the road, yet Toyota's (and Corollas especially it seems) are very blatantly aimed up, and at best are exactly level (which is still incorrect).

Honda drivers, on the other hand, seem to leave their high-beams on as a hobby. Over the 100k miles I've put behind the wheel of my truck in the past year, I could count on one hand the number of cars that have left their brights on, total. You'd need both hands to count the number of Honda's daily.

Isn’t there a knob to control the angle of the projectors? So that if you have heavy cargo at the back you can adjust the angle?

In the country I live in you’ll get honked to oblivion if you mess with that and blind the other drivers.

Uncommon in the U.S., sadly. My Jeep had that feature for the Canadian market, but not here, weirdly.

Technically yes, but you need a screwdriver to turn it. Just as well, most people wouldn't know how to turn it and make things worse.

Two of the five cars my family has owned in the last 20 years have had that feature.

No car I have ever seen in the US has this.

I assume they're aftermarket when they're on an early 90s economy cars, they're two different colors, and the refractor is scattering the light up past street signs -- not when they're just bright.

brightness isn't the issue, precision is.

Part of the problem stems from the fact that as cars age the headlight lenses oxidize and the original bulb's light becomes insufficient to light up the road ahead of the car. Some drivers are fixing the problem by swapping in much brighter aftermarket bulbs as opposed to replacing or resurfacing the lenses. It's easy to verify this by looking at the headlights of the offending cars after they've parked.

There are a few products that clear that up. I remember my mechanic doing it for me and it does make a noticeable difference. I would think any auto parts store would offer it to anyone buying bulbs as an up-sell.

In my experience at least, the cars I always have issues with are new ones with stock headlights, not modded cars. There are far less modded cars of course, but they always seem to be aimed lower to the road because they are lower cars in general.
