a light source unit comprising;

at least one semiconductor light emitting element,

a first light emitting part configured to emit red light of a first wavelength band, and

a second light emitting part configured to emit red light of a second wavelength band different from the first wavelength band.

2. The marker lamp according to claim 1,

wherein the first wavelength band includes a wavelength equal to or greater than 620 nm, and

wherein the second wavelength band includes a wavelength less than 620 nm.

3. The marker lamp according to claim 1, wherein the first light emitting part and the second light emitting part form a predetermined geometric pattern.

4. The marker lamp according to claim 1, wherein the first light emitting part and the second light emitting part are arranged on the basis of a predetermined repetition rule.

5. The marker lamp according to claim 1, wherein the semiconductor light emitting element is an organic EL element.

6. The marker lamp according to claim 2, wherein the first light emitting part and the second light emitting part form a predetermined geometric pattern.

7. The marker lamp according to claim 2, wherein the first light emitting part and the second light emitting part are arranged on the basis of a predetermined repetition rule.

8. The marker lamp according to claim 3, wherein the first light emitting part and the second light emitting part are arranged on the basis of a predetermined repetition rule.

9. The marker lamp according to claim 2, wherein the semiconductor light emitting element is an organic EL element.

10. The marker lamp according to claim 3, wherein the semiconductor light emitting element is an organic EL element.

11. The marker lamp according to claim 4, wherein the semiconductor light emitting element is an organic EL element.
