A '''Notification LED''' is a small [[RGB color model|RGB]] or [[monochrome]] [[LED]] light usually present on the front-facing screen [[Screen bezel|bezel]] (display side) of [[smartphone]]s and [[feature phone]]s whose purpose is to blink or pulse to notify the phone user of missed calls, incoming [[SMS]] messages, notifications from other apps, low battery warning, etc., and optionally to facilitate locating the mobile phone in darkness.<ref name="PhoneArena"> [https://www.phonearena.com/news/Versus-For-and-against-LED-notification-lights-in-phones_id114862 Versus: For and against LED notification lights in phones]</ref><ref>[https://beebom.com/how-customize-notification-led-behavior-android/ How to customize notification LED behaviour on Android - BeeBom.com]</ref> It usually pulses in a continuous way to draw the attention of the user. It is a part of the device's [[notification system]] that uses a [[Cloud computing|cloud]]-powered [[Push technology|push]] [[notification service]] to relay remote notification messages to the user, or local notifications. Similar to audio notifications, a notification LED is a very battery-efficient way to inform the user of new notifications without turning on the screen at all.
