VEHICLE SYSTEM REDUNDANCY

A computer system comprising processing circuitry configured to handle a lighting system of a vehicle. The lighting system comprises at least two redundant component groups each comprising a respective plurality of light sources and each being powered by a respective separate power source. The processing circuitry is further configured to: obtain diagnosis data of the lighting system, which diagnosis data is indicative of a status of the at least two redundant component groups in comparison with a predeterminable safety model; and in response to the diagnosis data indicating a fault or risk of fault associated with at least a first of the at least two redundant component groups, reconfigure the lighting system to utilize at least a first of the at least two redundant component groups not associated with said fault or risk of fault.
