A system for detecting obscurants on an outer surface of a lens of a vehicle lamp of a vehicle, comprising: a support; an infrared (IR) light emitter-detector module coupled to the support, the IR light emitter-detector module comprising: an IR light emitter configured to emit IR light towards an inner surface of the lens; and an IR light detector configured to measure an intensity of IR light reflected by the obscurants; and a controller coupled to the IR light emitter-detector module, the controller configured to: control the IR light emitter detector module; determine a level of light obstruction based on the measured intensity of reflected IR light; and when the level of light obstruction meets predefined criteria, issue a warning.
