1. A system to detect or determine vehicle lamp performance, comprising:
- a first optical sensor having a field of view which includes the location of a vehicle lamp or into which light from a vehicle lamp is emitted, the optical sensor providing an output indicative of vehicle lamp performance; and
a controller in communication with the first optical sensor to receive the output, the controller including at least one processor adapted to analyze the optical sensor output and provide a control output at least when the optical sensor output is indicative that the vehicle lamp performance is below a threshold.

10. A system to detect or determine vehicle lamp performance, comprising:
-
a plurality of optical sensors adapted to monitor an area around a vehicle which includes at least one vehicle lamp or light emitted therefrom into the area around the vehicle; and a controller that is couplable to the plurality of optical sensors, the controller comprising memory and at least one processor, wherein the memory is a non-transitory computer readable medium having instructions stored thereon for determining at the controller a degradation in vehicle lamp performance and providing an alert signal from the controller, wherein the instructions comprise; receiving one or more images from one of the plurality of optical sensors, at least a portion of the one or more images comprising a region of interest associated with the at least one vehicle lamp or the light emitted therefrom; determining an overall intensity of the one or more images; and when the overall intensity is less than a predetermined threshold, then; using the one or more images, determining whether vehicle lamp performance is degraded; and when vehicle lamp performance is degraded, then providing the alert signal. - View Dependent Claims (11, 12, 13, 16, 17, 18)

14. A method of determining a vehicle lamp performance at a controller in a vehicle, comprising the steps of:
-
receiving at the controller at least one image from an optical sensor wherein the at least one image comprises a region of interest associated with a vehicle lamp; determining at the controller an intensity of the region of interest; comparing the determined intensity to a threshold; and providing an alert signal from the controller when the intensity is below the threshold. - View Dependent Claims (15)
