lightning fire put out by rain creates ghost light

i was walking at night when suddently lightning struck 10 blocks away from me. it got extuingischt by the rain but the light emitted from the fire remained

what I expected to happen:the fire was put out by the rain and the light emitted by the fire would dissapear

what actually happened:the fire was put out by the rain and the light emitted by the fire stayed.

additional information: this does not happen ALL of the time. just sometimes
