A method () for identifying precipitation () includes the steps of: providing () a lighting unit () having a first photosensor (), a second photosensor (), and a controller (), where the first and second photosensors are vertically spaced by a first distance; receiving (), by the first photosensor, a first light signal from the precipitation at a first time point (T1); receiving () by the second photosensor, a second light signal from the precipitation at a second time point (T2); calculating () the amount of time between the first light signal and the second light signal; and calculating (), based on the first distance and the calculated amount of time between the first light signal and the second light signal, a velocity of the precipitation.
