Abstract: A motorcycle infrared rays lock for a motorcycle include a housing, an infrared rays receiving unit and a movable block contained in the housing and an infrared rays emitting unit. The infrared rays emitting unit is deposited in a separated case to be inserted in a front opening of the housing for turning on the emitter to emit a preset data signal to a sensor to actuate a receiving IC for examining the signal and turning on a transistor to actuate an electro-magnetic switch to retract a movable block. The movable block has a tooth end engaging a rack in an end portion of a hook rod locking a free end of a chain wound around a portion of a motorcycle wheel so that the chain can be taken off the hook rod and then off the wheel.

Abstract: A pair of flash eyeglasses has a switch positioned in a space between two screw projections at one end of a frame fitted with a flash light board therein. A skull temple has an ear at one end to be combined between the two projections in the frame with a screw so that the skull temple can swing open or closes with the screw as a pivot. A switch is placed in the space between the two projections in the frame to be pressed or released to turn on or off a circuit of the flash light board by the ear in the skull temple when the skull temple is swung open or closed.
