However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0023] The specific embodiments of the present utility model will be described below in conjunction with the accompanying drawings. Specific Embodiment 1:

[0025] Referring to Figure 1-6 , the present utility model provides a small-sized and long-life headlight, which includes a frosted bulb 1. The frosted bulb 1 includes a bulb 101. A connecting block 102 is provided at the bottom of the bulb 101. A condenser bulb 2 is provided at the center of the top of the frosted bulb 1. The condenser bulb 2 can concentrate most of the light therein and then emit light, which can make the brightness of the vehicle lamp more stable. The center of the top of the bulb 101 is connected to the condenser bulb 2 by fusion welding. A focusing lamp head 3 is provided at the bottom of the frosted bulb 1. The focusing lamp head 3 includes a lamp head housing 301. An inspection port 302 is provided on the front of the lamp head housing 301. The inspection port 302 can observe whether the internal structure and parts are loose and corroded, and can be replaced in time. A sealing ring 303 is provided at the top of the lamp head housing 301. The frosted bulb 1 and the focusing lamp head 3 are connected by screws.
