If at least one in the lamp which exists 24 becomes a life, it is designed so that all 24 lamps may go out.

LED is carried on the PWB of RUNTKA352, RUNTKA353, and RUNTKA354, and it is shown whether the lamp connected to which PWB became a

life.

LED of the PWB which the lamp has turned on normally is turned on, and LED of the PWB connected to the lamp which became a life goes out, it can
be known by LED whether the lamp connected to which PWB is a life.
