The license plate lamp pad pasting can play the effect of protection license plate lamp, because the vehicle is at the in-process of traveling, and the LED lamp face of license plate lamp LED circuit board is down received the rubble that splashes easily and is beaten, has had this layer of pad pasting and can effectively prevent the infringement, also prevents simultaneously that the sewage when washing from getting into in the tail lamp and causing the circuit short circuit.

Preferably, the LED circuit board of the brake position lamp is connected with the lamp holder through a screw. The LED circuit board of the brake position lamp and the lamp holder adopt the detachable connection mode, so that the installation is convenient, and the LED circuit board is convenient to recover and replace when the LED circuit board is invalid.

Preferably, a groove is formed in one end, close to the lamp shade, of the lamp holder, UV glue is arranged between the circumferential outer side wall of the lamp shade and the inner wall of the groove, and the circumferential outer side wall of the lamp shade is attached to the inner wall of the groove. The lamp shade and the lamp holder can be fixed together by the UV glue more firmly, no gap is left between the lamp shade and the lamp holder by the UV glue, the dustproof and waterproof effects are achieved, the UV glue is transparent, and the tail lamp cannot be influenced when the tail lamp penetrates through the lamp shade to illuminate.

Preferably, a structural adhesive is arranged between the rear cover and the lamp holder. There is no lamp bead near the back cover, so the back cover is fixed on the lamp holder by the structural glue with better bonding strength (the glue is not transparent).

Preferably, the LED circuit board of the brake position lamp and the LED circuit board of the license plate lamp are aluminum substrates, and the bottoms of the two circuit boards are coated with heat-conducting silicone grease. The aluminum substrate and the heat conduction silicone grease are good heat conductors, the LED lamp can generate heat after working for a long time, heat can be timely transferred to the lamp holder through the aluminum substrate and the heat conduction silicone grease, and heat dissipation is achieved through the surface of the lamp holder.

Preferably, the lampshade is made of a light-transmitting PMMA material, and the license plate lamp film is made of a light-transmitting PC material. The lampshade and the license plate lamp pad pasting are made of materials with good light transmission, the light spot effect emitted by the tail lamp is guaranteed to meet the requirement of riding, and the safety standard is met.

Compared with the prior art, the beneficial effects of the utility model are that: the whole tail lamp integrates a brake lamp, a position lamp, a license plate lamp and other lamps with various functions, so that the riding safety is improved; the design of the convex lens and the concave lens on the lamp shade can simultaneously project tail lamp light spots at the near and far positions of a vehicle, so that the illumination brightness and the illumination range of the tail lamp are improved, and the optical performance meets the requirements of different countries; the coated UV adhesive and the structural adhesive can enable the whole tail lamp to have waterproof and dustproof effects, and the waterproof grade IPX5 is achieved.
