To provide a remote control device for transmitting a light signal having a pulse pattern capable of reducing the possibility of false detection, a communication device including the remote control device and a sensor, a variable device further including an appliance whose state varies by tracking the remote control device, and a lighting device further including a moving light for illuminating the remote control device by tracking the remote control device. The remote control device transits a light signal having a pulse pattern to be detected by a sensor, in which the pulse pattern includes a first ON period, a second ON period, and an OFF period between the first ON period and the second ON period, the first ON period and the second ON period being repeated alternately, the first ON period and the second ON period are more than twice as long as a sampling time T of the sensor, the first ON period and the second ON period are different from each other, and the OFF period is longer than the sampling time T.
