。 This is a lighting circuit for a collective operation indicator light box that houses multiple indicator lights, and includes a series connection between a signal contact that closes when each required display state occurs and the corresponding indicator light, and a series connection between a manual switch such as a push button switch and an auxiliary relay. The connections are connected in parallel between the first and second control buses that supply the lighting power supply, such that each signal contact and manual switch in each of the series connections are on the first control bus side, respectively. Further, a lamp check bus is provided which is supplied with power from the first control bus through contacts of the auxiliary relay which are closed when energized, and furthermore, a lamp check bus is provided which is supplied with power from the first control bus through contacts of the auxiliary relay which are closed when energized, and furthermore, a lamp check bus is provided which is connected via each signal contact which is closed when the required display condition does not occur. In a collective operation indicator light circuit which connects each of the indicator lights and the lamp check bus, and which makes it possible to check for an abnormality of each of the indicator lights when the required display condition does not occur, the manual switch and the auxiliary switch are connected to each other. 1. A collective operation indicator lamp circuit, characterized in that a power supply shunt is provided from the first control bus to the lamp check bus, which is connected in series with a non-excited closed contact of a relay.
