You’re the man @Sasnuke . Last night another forum member, @Katran , tested his mirror on his 2022 and he said that his driver’s side mirror did dim, but very very slightly. I checked last night when I got his message and it appears to dim, just not very much. Like Katran experienced, it was very very dim. Almost negligible. It’s almost like you have to look for it in order to realize it. And you are correct in that there is no visible line. This is the same theory that @flipside909 had. From your experience with these vehicles, is the side mirror’s dimming very very light? It’s definitely not anything like the interior mirror. I feel like once I get tints I won’t even be able to notice the side dimming at all. Thanks in advance.
If you use the tape over the sensor that will give you maximum dim, anything else will be subject to how much ambient light there is.

The light sensor for the mirror that faint spot in the upper center of the mirror. Shine your flashlight or light source directly on the spot. Covering the sensor defeats the purpose of dimming the mirror.
I just took this from a 2022 IS 500 F SPORT Performance Launch Edition. It appeared to also dim the driver and passenger side mirror too, but where I tested it was in a brightly lit garage area with natural light.

This way the car thinks it pitch black out, so when you shine a light on the glass side of the mirror you get maximum dimming.
Thank you both for your help. I knew about the sensor in the front but I was unaware of the one in the back. So @Sasnuke trick of covering the sensor is what did it for me. The whole mirror dims, no visible edge. But it is worth noting that the EC on the side mirror is blueish, unlike the interior one which is green. And it is in fact only the driver’s side mirror. I appreciate the help of everyone who responded.
