Zusammenfassung:	This disclosure includes systems, methods, and techniques for controlling a plurality of light-emitting diodes (LEDs). For example, a circuit includes a switching device, where the switching device is electrically connected to an LED of the plurality of LEDs, and where the switching device is configured to control whether the LED receives an electrical signal from a power source. Additionally, the circuit includes processing circuitry configured to determine that the LED is associated with a bright failure condition by attempting to prevent the LED from receiving the electrical signal from the power source using the switching device and disable the LED in response to detecting the bright failure condition.
