Westchester County police and first responders returned to Maria Fareri Children's Hospital Tuesday to spread some Christmas cheer during the holiday season.

It was the fourth annual “Good Night Lights” event organized by the Westchester County police. 

A convoy of emergency service vehicles with a Blue Santa on hand, staged a drive-by parade of lights to illuminate the night sky for families and children at the hospital.

 Blue Santa also paid a visit to New York-Presbyterian Hudson Valley Hospital in Cortlandt Manor with lights flashing and sirens sounding throughout the day to bring smiles to hospital staff and patients.
