Abstract: A bicycle wireless indicating module for performing registration at a wireless control module of a wireless warning system is disclosed. The bicycle wireless indicating module receives and records a central control code of the wireless control module. When the wireless indicating module receives a coming control signal, the wireless indicating module matches if the coming control signal is in accordance with the recorded central control code. If yes, the wireless indicating module switches their indicating unit based on the received control signal, and forwards the control signal outbound. Thus, when a plurality of wireless indicating modules all records the central control code of the same wireless control module, the wireless control module is able to simultaneously control wireless indicating modules in the wireless warning system.

Abstract: A connector with an anti-loose fastening device has a housing, a socket module mounted inside the housing, and a plug module. The housing has a front opening for the plug module to insert in the socket module so as to electrically connect therewith. The housing has an elastic finger. The elastic finger has a tooth extending downwardly from one end thereof, and an inwardly slanted surface facing the front opening. When the plug module inserts in the socket module, the tooth of the elastic finger inserts in a recess formed on the plug module so as to prevent the plug module from disengaging with the socket module inside the housing.
