2. The vehicle lamp according to claim 1 , wherein the distance is adjusted such that optical path lengths of the light guided from the incidence section to the first light emission section are substantially equal.

3. The vehicle lamp according to claim 1 , wherein a plurality of reflection cuts are formed on the first light emission section.

4. The vehicle lamp according to claim 1 , wherein the second light guide section has a shape in which distances between the second end surface and the first light emission section and the third end surface and the light emission section are gradually decreased in the direction from the incidence section toward the first end surface.

5. The vehicle lamp according to claim 1 , wherein the second light guide section is disposed above and below the light source in a front view of the vehicle lamp.

6. A vehicle lamp comprising:

a light source; and

a light guide body configured to guide light from the light source,
