Four ways to read it
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream.
Freud
Freud would read a light brought into darkness as the wish to know, to see what is hidden in the self. A failing lamp can express anxiety about losing one's grasp on something.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might see the lamp as the light of consciousness carried into the unconscious, a small flame of awareness in the dark. Whether it holds or gutters can show how much insight you feel you have.

Continuity ties lamps to waking thoughts about understanding, safety, and finding your way. A lamp going out can echo a real fear of losing direction or hope.
Continuity hypothesis (our summary).Mythological
The lamp and lantern light the seeker's path through myth, from the wise virgins who kept their lamps filled to the magic lantern that summons aid. Light carried in the dark has always stood for knowledge and faith.
