Interesting. I couldn’t legally drive a car with high output headlights without it having both automatic adjustment and headlamp washers. It’s simply mandatory
Maybe you mean that it’s manually adjustable in addition to having auto-leveling? I think that’s the case for nearly all cars. Or maybe your car manages to stay below some sort of light output limit despite having LEDs.
What you’re talking about aren’t LED headlamps, these regulations (auto-leveling and washers) are mandatory for xenon headlights. LEDs don’t fall in the same category as xenon headlamps. What is interesting is that halogens have maximum allowed lumen rating which is a lot lower than what xenon headlamps can have and LEDs can have even more.
