The synopsis on www.play.co.uk says:
"Set in a time after the second World War, it's a magical story about two unforgettable friends. An abandoned, discarded Christmas bulb, afraid and alone... and an eight year old boy who finds him and takes him home. Broken and useless, Little Light is of no value to anyone - except to young Timothy who sees himself in Little Lights plight. Timothy's belief is so strong that Little Light can 'shine' again when the town suffers a blackout from a fierce winter storm, Little Light triumphs over all odds - and his own self doubt - to 'shine', lighting the way for others who 'see the light'."
It's a really sweet little story. :)
