@djsumdog @susie @Hoss >The height of the headlight doesn't matter. Headlights have a cutoff. Properly calibrated lights will have a maximum height of 2 inches below the center point of the enclosure at 25 ft.
Right, so prescribed rise/run of -2/300. Random glance shows cali had a permissible headlight height of 22~54 inches above ground, which translates to beams reaching 275~675 ft forward, but more importantly, I just measured my old camry's rear windscreen and it's about 43 inches above ground, so a 54inch high headlight is legally allowed to flood through it from 125ft away. FWIW they're allowed to be 59inches off the ground in various australian states.

>If you're getting blasted by a headlight, it's likely aftermarket and/or not installed correctly.
The frequency with which I noticed it from recent year SUVs half a decade ago lead me to believe it was stock. I haven't measured an SUV's headlight height and a few minutes of searching just had people avoiding the absolute numbers to talk about the relative drop requirement so I can't be bothered verifying if they actually are 50inches high, but it appears that it is perfectly legal for them to be high enough to pose a problem for cars.
