Question: I have questions about the legality, use/misuse and enforcement of laws regulating the use of HID and other ultra-bright or misaligned headlights on public streets. Far too often, I am literally blinded by oncoming vehicles using such headlights or seriously hindered by vehicles following me with searchlight-bright lights glaring in our rearview mirrors. This is especially problematic when the vehicles are trucks or large SUVs with high-mounted headlights.
Aren’t such headlights banned from public streets? Why is there seemingly no enforcement of these laws? Almost as bad are the numerous headlights that are terribly misaligned so that they shine directly into oncoming driver’s eyes. I remember years back when annual inspections required a headlight alignment check, for very good safety reasons. Whatever happened to end those requirements? And, in lieu of annual inspections, can police cite vehicles with misalignment problems?
Finally, what liability do drivers incur who use HID or other ultra-bright headlights that cause accidents?
Answer: Your question raises a number of issues covered by a variety of laws. The following RCWs cover some of the issues you raise. They are not quoted completely due to length.

The minimum height from the ground for headlights is 2 feet; the maximum is 4 ½ feet. There are minimum and maximum distances they are allowed to shine as well. They are never supposed to shine into another driver’s eyes. There are a maximum number of lights that are allowed to be illuminated at any one time. All lights offered for sale in the state are supposed to meet standards set by the Washington State Patrol.
I don’t recall Washington ever having a mandatory annual inspection for vehicles, except for a few counties that had to have emissions checks to get license tabs. Never having lived in those counties during that period, I don’t know if the light check would have been part of that or not.
Police could issue either warning notices or traffic infractions for violations of any of the RCWs. The minimum and maximum height of head lamps and the number of illuminated front lights are probably the only RCWs that might be enforced.
For the liability question, that is best taken up with an attorney. If the headlights are shown to be of an illegal type, or are somehow the cause of the crash, there may be some liability issues.
Here are excerpts of the relevant laws:
RCW 46.37.040 Head lamps on motor vehicles.

(2) There shall be a lowermost distribution of light, or composite beam, so aimed and of sufficient intensity to reveal persons and vehicles at a distance of 150 feet ahead; and on a straight level road under any conditions of loading none of the high intensity portion of the beam shall be directed to strike the eyes of an approaching driver.
