HiLight Studio, a third‑party app by Dhananjay_Tech, lets the Pixel 11 Pro’s HiLight LED do rainbow pulses, waves, and other colors and animations, with adjustable timing, brightness, and presets. It isn’t on the Play Store yet and requires sideloading and enabling developer options to run.
Pixel 11 Pro's HiLight LED is restricted out of the box, but the open-source HiLight Studio app expands it into a configurable notification LED with custom colors and patterns (e.g., comet, pulse, rainbow), per-app rules, presets, and a Quick Settings toggle. Setup requires sideloading the APK and using Shizuku for wireless debugging to grant necessary permissions; the LED has built-in safety limits (auto-dimming after 10 seconds, default 30-second off for app-triggered lighting, max 5 minutes per activation, and a global 5 minutes per 10-minute window). Some testers report stability caveats or occasional interference with the base HiLight functionality, but the app showcases how Google could have offered more control from the start.
