4. The utility vehicle signal lamp of claim 1, wherein: the first light-emitting area is red, and the second light-emitting area is transparent or white.
5. The utility vehicle signal lamp of claim 1 or 4, wherein: the first LED light source and the third LED light source are red light sources, and the second LED light source is a white light source.
6. The utility vehicle signal lamp of claim 1, wherein: the number of the first LED light sources, the second LED light sources and the third LED light sources is multiple, and the number of the second LED light sources and the number of the third LED light sources are equal; the number of the first reflecting cups is equal to that of the first LED light sources and corresponds to that of the first LED light sources one by one; the number of the second reflecting cups is equal to that of the second LED light sources, and the second reflecting cups are in one-to-one correspondence with the second LED light sources.
7. The utility vehicle signal lamp of claim 6, wherein: the first reflecting cup and the second reflecting cup are integrally formed on a supporting plate and distributed in an array on the supporting plate.
8. The utility vehicle signal lamp of claim 1, wherein: the reflection surfaces of the first reflection cup and/or the second reflection cup comprise a first reflection surface and a second reflection surface which are distributed along the circumferential direction of the cup wall of the first reflection cup and/or the second reflection cup in sequence, the first reflection surface protrudes out of the second reflection surface, light rays reflected by the first reflection surface realize large-angle light emission, and light rays reflected by the second reflection surface realize small-angle light emission.
9. The utility vehicle signal lamp of claim 1, wherein: the reflecting surfaces of the first reflecting cup and/or the second reflecting cup are all or partially set to be grating surfaces, and each grating surface in the grating surfaces is respectively not coplanar with the adjacent grating surfaces.
