[[File:Notification LED Huawei.webm|thumb|A notification LED on a smartphone]]
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.

Starting 2019 most smartphones vendors have stopped adding the notification LED which could be explained by the advent of [[Always-on display|AOD]] and a drive for smaller bezels.<ref>{{Cite web |last=Rahman |first=Mishaal |date=2019-07-21 |title=NotifyBuddy uses your phone's AMOLED display as a notification LED |url=https://www.xda-developers.com/notifybuddy-amoled-notification-led/ |access-date=2023-10-24 |website=XDA Developers |language=en}}</ref><ref>{{Cite web |date=2022-03-05 |title=The notification LED is almost dead, but one phone convinced me it should return |url=https://www.androidauthority.com/smartphone-notification-led-return-3120909/ |access-date=2023-10-24 |website=Android Authority |language=en}}</ref>

The notification LED light was popular when [[feature phone]]s were widely used. In early smartphones running [[Windows Mobile]] or the [[Android (operating system)|Android]] operating system, the LED notification light was also a fairly common feature. These smartphones usually had LCD
Gradually, the smartphone industry has been moving towards [[OLED]] displays. With this transition, the dedicated notification LED light has slowly been eliminated from newer smartphones. There is also a focus by smartphone designers to minimize the screen bezels or keep them very thin, thus leaving no room for the notification LED light.
As a replacement for the LED light, some smartphones from Samsung, LG, and Nokia include an [[Always On Display]] feature. On OLED displays, the Always-On Display (AOD) shows limited information while the phone is asleep, that is, when the entire display is not lit up. With OLED screens, only a part of the screen, or a few pixels on it can be turned on to convey information.
With any pixel on an OLED screen effectively being a notification LED, software can be used to customize its appearance. It can blink or pulse like a light continuously, or some phone manufacturers light up the display's pixels like a ring or have edge lighting.

|The phone uses Red, White, and Green (follows battery level) for generic notifications. Otherwise, the phone follows the LED color that the app uses.
