Also, the present invention can enable a turn indicator lamp composed of an LED part (6) to be operated, or a brake lamp function to be performed by selectively pushing each key of a key part (4) and can enable a module (22) to be separated from a grip part (37), and the grip part (37) to be tightly fixed to the handle bar (50). ## Claims ### Claim 1 A multi-functional turn signal lamp for a bicycle, comprising: a grip part installed at an end of a handle bar of the bicycle and having a key part composed of an on/off key, an output key, a turning on and off/accelerating or decelerating key, and a headlamp key; a battery part embedded in the grip part and electrically connected to a terminal installed at the grip part; a substrate connected to the battery part; an LED part installed to be electrically connected to the substrate and composed of multiple LEDs; a cover in which a speaker is embedded; and a lighting part for illuminating a beam from the LED part in all directions. ### Claim 2 (depends on 1) The multi-functional turn signal lamp of claim 1, wherein the LED part is installed at a back mirror, or the LED part is configured to be mounted via a multi-link in the case of a drop bar form, and a length on one side of the LED part from the center of a length of the handle bar ranges from 100 to 500 mm. ### Claim 3 (depends on 1) The multi-functional turn signal lamp of claim 1, wherein the LED part is installed on a circumferential portion of an inner circle of the cover to have regular intervals or multi-rows and includes various LEDs for transmitting turn indicator, sidelight and accelerating or decelerating signals, an LED serving as a brake lamp, and a high luminance LED serving as a head lamp. ### Claim 4 (depends on 1) The multi-functional turn signal lamp of claim 1, wherein a charging terminal capable of charging a portable device and a portable repository inserting part are installed at the key part. ### Claim 5 A multi-functional turn signal lamp for a bicycle, comprising: a grip part installed at an end portion of a handle bar of the bicycle and having a key part composed of a power and headlamp key, a turn indicator key and a brake lamp key; a module detachably attached to the grip part via a hook; a battery part embedded in the grip part to be electrically connected to a terminal; an FPCB (Flexible Printed Circuit Board) and a PCM or PCB (Protection Circuit Module or Board) for electrically connecting the battery part and an LED part composed of flash LEDs, a turn indicator LED, a brake LED; a lighting part installed at the module to illuminate a beam of the LED part in all directions; and a ring installed at an end of the module to enable a hook to be turned on or off. ### Claim 6 (depends on 5) The multi-functional turn signal lamp of claim 5, wherein a locker part is also pulled when the ring is pulled, and at the same time, a pin is horizontally moved so that a hook top and a hook bottom of a hook can be moved to the center, thereby enabling the module to be separated from the grip part. ### Claim 7 (depends on 5) The multi-functional turn signal lamp of claim 5, wherein an O-ring for waterproof is installed in an inner side of the module. ### Claim 8 (depends on 5) The multi-functional turn signal lamp of claim 5, wherein an FPCB (Flexible Printed Circuit Board) and a pogo pin are connected to each other upon connecting the grip part and the module so that signals can be transmitted or received. ### Claim 9 (depends on 5) The multi-functional turn signal lamp of claim 5, wherein a clamp is installed at both ends of the grip part so that the grip part can be firmly connected to the handle bar of the bicycle via a means for attaching or detaching the clamp. ### Claim 10 (depends on 5) The multi-functional turn signal lamp of claim 5, wherein a pair of hooks is formed at an end of the module, and a projection part is formed in an inner side of a circular ring in which multiple elastic pieces are formed at an outer side so that the hooks can be insertedly fixed into the projection part, and the elastic pieces can be elastically connected according to a thickness of the handle bar of the bicycle. ### Claim 11 A multi-functional turn signal lamp for a bicycle, which is configured such that a grip part and a module are detachably attached to each other, the multi-functional turn signal lamp, comprising: the grip part; the module; a key part formed at one side of the grip part and composed of a power and headlamp key, a turn indicator key and a brake lamp key; a control part for controlling turning on and off of a head lamp, a turn indicator, and a brake lamp each including LEDs according to a key signal of the key part; and a clamp installed at both ends of the grip part to firmly fix the grip part to a handle bar of the bicycle, wherein the key part is connected to an LED PCB (Protection Circuit Board) via an FPCB (Flexible Printed Circuit Board) and a pogo pin, a negative terminal and a positive terminal of a battery are connected to the LED PCB, and a hook part is installed in an inner side of a silicon cap of the module so as to enable the module to be detachably attached to the grip part. ### Claim 12 (depends on 11) The multi-functional turn signal lamp of claim 11, where the hook part includes: a top hook; a bottom hook; and a spring elastically installed between the top hook and the bottom hook. ### Claim 13 (depends on 11) The multi-functional turn signal lamp of claim 11, wherein a double waterproof structure for waterproof is formed in an inner side of the silicon cap where the silicon cap and the grip part come into contact with each other. ### Claim 14 (depends on 6) The multi-functional turn signal lamp of claim 6, wherein an O-ring for waterproof is installed in an inner side of the module.
