Is this a rain sensor??

[LMACYBERTRUCK]

Just took delivery of a 2025 CB and noticed what looks like a rain sensor on the top of the windshield cameras-is it new or already existing and maybe some light sensor?

GROK:The Tesla Cybertruck does not have a traditional rain sensor. Instead, it relies on camera-based systems for its auto-wiper functionality. This information can be inferred from the absence of a rain sensor in the Cybertruck's parts catalog, which only mentions a cabin radar and not a front radar sensor or a traditional rain sensor for the windshield. Additionally, discussions on forums like the Tesla Motors Club and Cybertruck Owners Club indicate that Tesla has moved away from using physical rain sensors in favor of camera-based detection for newer models, including the Cybertruck.[](https://teslamotorsclub.com/tmc/threads/tesla-where-are-my-hw2-auto-rain-sensing-wipers.96439/)[](https://www.autoevolution.com/news/tesla-cybertruck-doesn-t-come-with-a-radar-sensor-like-model-s-x-parts-catalog-shows-226094.html)

Look like you guys have done a good job of digging around in the service manual, I looked over it too and wasn’t able to find anything conclusive but the clear lens kinda facing up and what I’ve seen in a few other vehicles I’ve had and worked on.. I think it’s an ambient light sensor. When I get back home in a few days I’ll put a beanbag or something on it while in the driveway in the daylight and report back
