Without seeing the proprietary internal designs or other testing data from various manufacturers, it's hard to pinpoint exact reasons for certain perceived headlight anomalies. Could be a tuning aspect to pass certain regs/certification, could be a shadow of a technical part. Could be anything. Hard to say without tearing apart the headlight (of which i tore apart many over the years) Pretty much if it's on both sides, it's likely normal. If it's on one side, it's also likely normal. Headlights are very technical and can exhibit "anomalies" which are "weird" to your average layman. It's not for you to worry about as it's an engineering byproduct which is inconsequential to the end user.

25+ year of high end headlight modding and I've seen all sorts of shadows and anomalies, and even created some myself using various mods, plates, washers, shims, sloped cutoff plates, etc. We used to tune in or out various things in the headlight projection. I used to make custom plates back in the day and tuned in color using lenses and washers. The tiniest change will exponentially magnify over very large distances. So what you're seeing is tiny tiny tiny tiny on the headlight, but looks large when projected out onto the wall/road.

In the end don't worry about it.

 

My has this as well, noticed it first night drive. 350 without triple beam.

 

It's not a worry problem. It's a distraction problem when driving at night. I've never seen this "feature" in any other headlight.

 

I agree it is very much a distraction. This is the first car I have ever had with such a strange shadow. It is on both sides but I only find it distracting on the driver’s side.

 

Have you had any success with getting rid of the shadows? This could very well be the cause. I see the same shape in my garage when car is only a few feet away from the wall. However, on the road the shadow is much larger and downright distracting on the driver’s side.

 

My Audi had these shadows as does my Lexus. I believe they are made this way. Supposed to avoid blinding oncoming driver.

 

That's what I assumed too... shadows only at top edge of oncoming car position about where that driver and passenger would be facing.

 

Greetings. Love my new RX350 except the headlights. When dimmed, there is a rainbow at the top and an L looking contraption hanging down from each side. Have contacted my dealer and Lexus HQ. It really is annoying. Does anyone else have this. Purchased in AUG 2024.

 

A picture would help.

What do you mean by when dimmed?

 

There are different headlamps depending on trim level and country. Canadians have more options!

I second the request for a picture showing the light pattern, and the car's light configuration when off.


PS: Many of us have benefited from turning the headlight aim 1.5 - 2.0 full turns 'higher'. Do a SEARCH for the topics here.

 

I believe there are other posts on this subject. My lights have those same L shaped dark spots on my standard settings. I believe they reduce glare to other drivers but not sure

 

I have the same on both sides. Hate this!!! Distorts my vision.

Using dim beam, not on high beam/

My car was made in Canada. I live in Florida.

Could not agree more. It is very distracting at night.

This is exactly what my "L" things look like, both driver and passenger side. I noticed it immediately when driving home. It is a true impediment when driving at night with the dim lights.

 

These are what show up when driving with low beams on. What I refer to as dim lights.


please see photo I posted. Thanks.
