器。 Light emitting diode units, each consisting of two light emitting diode chips of different light emitting colors connected in antiparallel, are placed in the center of the printed wiring board, and several units are placed in a ring around the printed wiring board. Light emitting diode chips of the same color (excluding the unit) are installed so that they are connected in series with the same polarity, and this printed wiring board is assembled into a housing. When it is attached so as to be connected to the printed wiring board through a lead wire and is attached to a socket whose polarity is to be determined, the center part and the ring part around it emit light in different colors, and one of the light emitting colors 1. A polarity determiner, characterized in that the polarity of a power source is determined depending on whether the power source is at the center or at the annular portion.
