When such river, stream or bay is navigable, the company shall, for the safety of persons navigating the same, maintain a red light at each outer side and a white light at each inner side of said draws, which shall be kept lighted between sunset and daylight. The company shall also keep a suitable person at each bridge or viaduct to open the draws for the free passage of all vessels with standing masts or pipes.
For each neglect to keep such light and to open the draws when necessary, the company shall forfeit one hundred dollars, to be recovered with costs in any court having jurisdiction thereof by any person suing for the same within six months after the time of such neglect.
