Abstract: A fastener frame with a button switch incorporated is provided which includes a socket unit (E) connected to a belt (8) with the belt (8) having sources of luminosity (81). When a plug (6) is connected to the belt socket (14), lugs (611) on the front end of plug rod (61) are engaged within setting holes (141). Simultaneously, a starting rod (62) formed at the middle of the plug (6) presses against a push button (31) mounted on a driving circuit module (3). Initiation of the push button (31) initiates the driving circuit to energize the sources of luminosity (81) as well as the luminous sources (25) formed in a top cover (2). In this manner, a warning device is provided which alerts drivers of passing vehicles that the wearer is in the vicinity.

Abstract: A portable light generating belt device includes a housing having an aperture, a fixed shaft, and a retaining unit disposed on an outer surface of the housing. A pulley includes a pulley body which is disposed rotatably on the shaft of the housing, an annular groove which is formed in an outer surface thereof, and a cavity which is formed in a side wall of the pulley body. A torsion spring is received within the cavity of the pulley body and is secured at one end portion thereof to the shaft of the housing and at the other end portion to the pulley body. A light generating belt is provided with an electroluminescent strip which can be powered to generate light, and has an inner end portion which is secured to the pulley and an outer end portion which extends through the aperture of the housing. An enlarged end of the belt is located outside of the housing and is sized so that the enlarged end cannot pass through the aperture into the housing.
