Many smartphones except Apple iPhones are equipped with low-power [[light-emitting diode]]s besides the screen that are able to notify the user about incoming messages, missed calls, low battery levels, and facilitate locating the mobile phone in darkness, with marginial power consumption.

To distinguish between the sources of notifications, the colour combination and blinking pattern can vary. Usually three diodes in red, green, and blue ([[RGB]]) are able to create a multitude of colour combinations.
