Abstract
A system includes at least one sensor; a plurality of lamps fixed relative to the sensor; at least one vehicle component attached to the lamps; and a computer communicatively coupled to the lamps, the at least one sensor, and the at least one vehicle component. The computer is programmed to sequentially activate the lamps, determine that an intensity for at least one of the lamps is below a respective intensity threshold based on data from the sensor during the sequential activations of the lamps, and actuate the at least one vehicle component in response to one of the intensities being below the respective intensity threshold.
Claims19
A computer comprising a processor and a memory storing instructions executable by the processor to:
- sequentially activate a plurality of lamps fixed relative to each other;
- determine that an intensity for at least one of the lamps is below a respective intensity threshold based on data from a sensor during the sequential activations of the lamps;
- in response to one of the intensities being below the respective intensity threshold, increase a voltage to each lamp having an intensity below the respective intensity threshold by an amount proportional to a difference between the respective intensity threshold and the respective intensity;
- and
- in response to one of the intensities being below the respective intensity threshold, actuate at least one cleaning system to clean the lamps that have intensities below the respective intensity thresholds.
