A little wordy, perhaps a little too in depth, but a great article on proper aiming.

General rule of thumb:

Locate the headlight adjustment screw before starting, and see what tools you need to adjust it. A screwdriver is normally all that’s needed, but it depends on the vehicle.

Ensure the headlights are in low and not on bright/high.

Park on a flat level surface, with the headlights aimed at a wall approximately 25 feet away. Can pace it out, just needs to be close.

With a measuring tape, measure from the ground in front of the car to the center of the headlight assembly. Take that measurement, and subtract 2.5 inches. (Eg, 30 inches now becomes 27.5 inches.)

Head over to the wall, and measure from the ground to the center of the bright spot the headlights make on the wall.

The bright spot should be at 27.5 inches as per your measurement.

If not, open the hood and locate the headlight adjustment screw. Turn the screw, one direction will raise the light and the other will lower it. Turn the screw until the bright center of the light is at the correct height (27.5 inches in this example). Repeat for both lights.

This will get you close enough 99% of the time!

Self-leveling headlights account for bumps, that’s literally their purpose.

For the record, I did say that lights are too bright. I don’t disagree at all. But there are two distinct issues at play here, and both need to be addressed.

I’d also like to see enforcement of proper headlight aiming. While lights really are too bright, it’s crazy that no one aims them properly.

An educational program about proper aiming, along with a check stop style safety sweep would help mitigate a lot of the issues.

Then again, we could just do the smart thing and mandate auto-leveling headlights, but that would be too simple.

Sounds to me like a parenting issue, not a valve issue.

Salient points for those who don’t want to read the article, or can’t:

• The team administered a single shot of E. americana intravenously to mice with colorectal cancer, and it completely eliminated tumors in every treated animal.

• Caused only short-lived inflammatory effects that resolved within 72 hours

• Over two months of observation, treated mice showed no signs of organ damage or chronic toxicity.

• The bacterium are also sensitive to antibiotics, providing intervention options if problems were to arise following treatment.

• When the mice were later re-exposed to cancer cells, none developed new tumors, suggesting the treatment had triggered long-lasting immune memory.

This holds some real promise, I’m very excited to see what this brings! Kudos to the researchers!
