Systems and methods provide a first light source (40), a second light source (41), and a controller (73) communicatively coupled (70) to the first light source (40) and the second light source (41). The controller (73) controls a first operation of the first light source (40) according to an input received by the controller (73) for at first period of time, and to control a second operation of the second light source (41) when the input received by the controller is in a second period of time that is greater than the first period of time. |
