A fitness equipment unit has a controller that actuates a light between different states in response to service conditions. In one implementation, actuation of the light is based upon a combination of at least two of: a mileage parameter of the fitness equipment unit, a sensed electrical current of the fitness equipment unit, a sensed temperature from the fitness equipment unit and a sensed position of a portion of the fitness equipment unit. In another implementation, actuation of the light is based upon a combination of the first and second service conditions selected from a group consisting of: a connection error service condition; a part wear service condition; a motor/actuator error service condition; a sensor error service condition; a processor error service condition; and a power supply error service condition and further based upon a prioritization of different severity levels of the first and second service conditions.
