1. A flashlight, comprising:
- a light emitting diode (LED);
a controller configured to, in a programming mode of operation, receive a programming signal generated by the LED in response to illumination of the LED with an externally-supplied light signal modulated with the programming signal; and
a first switch, wherein the controller is configured to transition between the programming mode of operation and a normal mode of operation with respect to an actuation of the first switch.
