A Harlem building super says he lost his job when he refused to put up holiday lights last year because it conflicted with his religious beliefs.

Nelson Santamaria, a Jehovah’s Witness who worked at 1919 Madison Ave., for more than a decade, was asked to string up the lights but declined, according to a Manhattan Supreme Court lawsuit filed last week. Not long after, he was sacked.

The management companies, being sued for $2 million, did not comment.
