Anyone with an ES with Triple Beams - do your headlights cast this display with the inverted "triangles?" To me, this is like the little rattle or creak that just urks you! It's nit-picky but oh well. At times they are more prominent.
yeah, it appears to be a triple beam thing and it is affecting other Lexus models as well. Under certain conditions some people describe it as a wide "U".

Thanks! I forgot to mention that it usually casts more on the driver's side or slightly left of the middle.
Depending on the lightning supplier it can be more noticeable but it is there in one form or another. Below is an explanation from a LED expert:
"That shadow is done to comply with the US lighting regulation standard that requires test point 0.86D/3.5L to have a minimum intensity of 1800 candela and no greater than 12,000 candela. The reason for this restriction is unknown but it is believed to avoid glare from wet pavement to oncoming drivers during inclement weather.
If you look at every LED headlamp of every car brand you will see that the lighting supplier has, in some form or another, implemented a way to shade this test point. Some are very noticeable while others are barely noticeable. Some beams are developed with a slope rather than a shadow to circumvent that test point."

I've been tuning and modding specific projection characteristics for over 20 years. The tiniest adjustment/spacing can create a massive effect as the shape/pattern/cutoff is amplified 200 yards down the road.
But really lightning is none of anyone's concern in 2022. Everything is highly computerized & standardized in cad. Whatever it is it is. There's nothing to be annoyed at, concerned about etc. That's what the engineers designed and it's not for the end user to be concerned about. you guys worry about the wrong things.
Be proud of and boast about whatever the result is. Just know it's highly designed and engineered and it's very good (whatever it is). Highly standardized and highly normal!

The beauty of prerogative is it's highly subjective. My right to be annoyed is just as valid as your right to make so many self-righteous comments. I'm sure you have expertise in certain areas and on this topic your opinion probably does matter to someone, just not to me! And that's just my opinion. Thanks for weighing in, love it!
Kinda like fangs. How appropriate that they are only visible in the dark. I never thought about it like that. Thanks for pointing that out!. I love it too!
Can confirm that I have the same thing on my 2019 ES300h UL. I only have that triangle on the left driver side and always thought that it was to prevent glare for the drivers on the opposite side of the road. I always wanted to signal the ''problem'' to the dealership during services, but got used to it eventually (I don't really notice it anymore ; about 90 000KM on the clock)
