A light guide bar 5 is integrally formed at the bottom of the light distribution mirror 2, and a first light strip 6 and a second light strip 7 are integrally formed on the upper end face of the light distribution mirror 2. A pin terminal seat 8 is provided on the LED light circuit board 4, and two pin terminals 9 connected to the LED light circuit board 4 are provided on the pin terminal seat 8. A slot 10 is provided on the inner side of the end of the lamp holder 1, and a socket 11 connected to the slot 10 is provided on the outer side of the lamp holder 1, and the front end of the pin terminal 9 is placed in the slot 10. The slot 10 is provided with a connector plug 12 connected to the LED lamp circuit board 4. The connector plug 12 includes a plug housing 13 adapted to the slot 10, two socket terminals 14 inserted into the plug housing 13 and plugged into the pin terminals 9, and a sealing plug 15 connected to the rear end of the plug housing 13 and adapted to the socket 11. The front end of the plug housing 13 is provided with two pinholes 16 for inserting the pin terminals 9. The socket terminals 14 are inserted into the terminal insertion cavity of the plug housing 13 and fixed by retaining clips 27 on both sides.
