4. The corridor indicator lamp according to claim 1 , wherein the extension unit comprises at least one pocket, which is configured to receive at least parts of one of the plurality of separator walls.

5. The corridor indicator lamp according to claim 4 , wherein at least one of the plurality of extension walls is aligned with the at least one pocket of a plurality of pockets.

6. The corridor indicator lamp according to claim 4 , wherein the at least one pocket covers only part of the associated separator wall.

7. The corridor indicator lamp according to claim 4 , wherein the at least one of the plurality of extension walls extends from the at least one pocket of a plurality of pockets.

8. The corridor indicator lamp according to claim 1 , wherein at least some of the extension walls are provided with at least one predetermined breaking line, wherein the at least one predetermined breaking line is located between at least one of the plurality of extension walls and an associated pocket.

9. The corridor indicator lamp according to claim 1 , wherein at least one of the plurality of extension walls is provided with at least one cutout which is shaped complementary to an associated one of the plurality of separator walls.

10. The corridor indicator lamp according to claim 1 , wherein the extension unit is configured to be releasably mounted to the base assembly.

11. The corridor indicator lamp according to claim 1 , wherein the at least partly transparent cover has a convexly curved shape corresponding to distal edges of the extension walls, wherein the distal edges of the extension walls contact an interior surface of the cover along an entire width of the distal edges.

12. The corridor indicator lamp according to claim 1 , further comprising an elevation socket, the elevation socket configured to be attached to the base assembly opposite the plurality of separator walls.

13. A kit for assembling a corridor indicator lamp, comprising:

a base assembly, the base assembly including a plurality of compartments, which are open towards a front side of the corridor indicator lamp, and a plurality of separator walls, at least some of the plurality of compartments being separated from each other by at least some of the plurality of separator walls;

an extension unit, which is configured to be mounted to the base assembly and which has a plurality of extension walls, which, in a position where the extension unit is mounted to the base assembly, extend at least one of the plurality of compartments in a direction pointing away from the base assembly; and

a first cover and a second cover, wherein the first cover or the second cover is at least partly transparent and configured to receive the extension unit, and wherein the first cover protrudes at a greater height from the base assembly than the second cover, the first cover and the second cover being configured to be alternatively mounted to the base assembly.

14. The corridor indicator lamp according to claim 1 , wherein the extension walls enlarge at least one of the plurality of compartments of the base assembly in the direction pointing away from the base assembly.
