This paper proposes a new indoor positioning system that utilizes home lighting. We design a beacon for use in the system that is inserted between a home light bulb and its socket, and is supplied with electricity from the socket. This means that the end user can easily install the system in his/her environment. In addition, we propose a fingerprinting-based indoor positioning method that employs signals received from the beacons. Because the ON/OFF states of our beacons change according to the ON/OFF states of the lighting, the signal strengths from the beacons also change greatly and this reduces positioning accuracy. So, we improve the positioning accuracy by estimating the ON/OFF states of the lighting based on the residents’ life patterns.
