Each of the plurality of drivers includes a control unit that controls the load driving element directly associated with a subject driver. The respective drivers are electrically connected to one another so that a mutual control communication state, in which the control unit of the subject driver can transmit to the control units of all or a portion of target drivers of other drivers excluding the subject driver a command signal for controlling the driving of a load driving element directly associated with the all or the portion of target drivers, is created in the load control system. ## Claims ### Claim at position 1 1-4. (canceled) ### Claim 5 A load control system comprising: a plurality of drivers provided correspondingly to a plurality of load driving elements in order to control driving of the respective load driving elements for driving loads, each of the plurality of drivers includes a control unit that controls the load driving element directly associated with a subject driver, and the respective drivers are electrically connected to one another so that a mutual control communication state, in which the control unit of the subject driver can transmit to the control units of all or a portion of target drivers of other drivers excluding the subject driver a command signal for controlling the driving of a load driving element directly associated with the all or the portion of target drivers, is created in the load control system, the control unit of each of the plurality of drivers included in the load control system is formed such that, when one of the plurality of drivers is replaced with another driver, and the other driver excluding the driver who has been replaced among the plurality of drivers outputs the same command signal as the command signal for the replaced driver to the other driver which is a replacement driver, the load driving element directly associated with the other driver which is the replacement driver executes the same predetermined operation as the load driving element directly associated with the replaced driver. ### Claim 6 (depends on 5) The load control system according to claim 5, wherein the mutual control communication state is maintained in the load control system regardless of a form of mutual connection among the plurality of drivers. ### Claim 7 (depends on 5) The load control system according to any one of claim 5, wherein in the load control system, all of the respective drivers are connected in series or a portion of the plurality of drivers is connected in parallel to one driver included in the plurality of drivers. ### Claim 8 (depends on 5) A load driving system comprising: the load control system according to any one of claim 5; the plurality of load driving elements corresponding to the plurality of drivers included in the load control system; and a power supply unit that supplies power to the plurality of load driving elements. ### Claim 9 (depends on 6) The load control system according to any one of claim 6, wherein in the load control system, all of the respective drivers are connected in series or a portion of the plurality of drivers is connected in parallel to one driver included in the plurality of drivers.
