Zusammenfassung:	A light sensor suitable for use with a light assembly 2 includes a light receiver 18 and a controller 16 connected to the light receiver, wherein the light receiver receives a light input including ambient light and converts the light input into an output signal and the controller receives the output signal. The controller calculates the level of ambient light either by determining the level of light emitted by the light assembly by monitoring a modulated component of the light input and subtracting it from the total light input, or by only calculating the level of ambient light incident on the sensor when the light assembly output is substantially zero, which may be determined from knowledge of a pulse frequency of the light assembly.
