1. A controller for a barrier operator, comprising:
an energy source configured to provide a current to the controller;
a sensor configured to determine whether a predetermined event is satisfied and generate a modulation signal based on the predetermined event;
wherein the sensor comprises an ambient light sensor, a switch, a timer, a proximity sensor, or combinations thereof, and/or wherein the light source comprises a light emitting diode;
wherein (a) the sensor comprises the ambient light sensor, and wherein the ambient light sensor is configured to determine an amount of light proximate the controller and to generate the modulation signal in response to the amount of light, (b) wherein the sensor comprises the switch, and wherein the switch is configured to be actuated by a user and to generate the modulation signal in response to actuation of the switch, and/or (c) the sensor comprises the timer, and wherein the timer is configured to determine when a predetermined amount of time has lapsed and to generate the modulation signal during or after the predetermined amount of time;
a dimming device communicatively coupled to the sensor and the energy source, the dimming device configured to generate at least one of a modified current or a modified voltage in response to the modulation signal; and
a light source electrically coupled to the dimming device and configured to illuminate in response to at least one of the modified current or the modified voltage, wherein the light source is a status indicator for an operational parameter in the controller for the barrier operator.
