By Philly.comPARSIPPANY, N.J. - Once again, mysterious red lights in the sky have residents in north-central New Jersey scratching their heads.
It's the third time in about a month that Morris County residents have reported seeing the lights.
Police in Morris Plains, Morris Township, Hanover and Morristown each reported getting a few calls from residents last night night.
The callers say they saw as many as 10 red lights floating in the sky, moving in unison and in the same direction as the wind from about 8:45 p.m. to 9 p.m.
No one knows where the lights are coming from, but a Michigan-based maker of Sky Lanterns says it could be his product. The lanterns have balloons and wax-infused cloth and are set aloft during celebrations.
