The are a few explanations for such phenomenon. The Italian scientist A.Volta, the discoverer of Methane gas, believed such lights are often reported to occur only in swamps and marshes and the main reason for the glowing nightly lights is ionization of methane. The source for the production of methane is decaying organic matter that is available in plenty in the water-logged swampy or bog lands.
Gases such as phosphine, diphosphane and methane are products of decaying organic matter and tend to oxidize upon contact with oxygen. After ionization, the molecules of these gases cause packets of light - photon. The color variation is due to different gas and wavelengths.The duration of lights depends on the amount of methane in the swamps' decaying organic matter.
One earth scientist attributes the lights to piezoelectric, property in quartz, silicon, or arsenic that may also produce sparks of electricity during some geologic faulting and associated frictions of two moving blocks of rocks on opposite sides.The sparks might ignite the available methane in that area. These instances are rare and may occur in only in tectonic regions.
