The present disclosure relates to a method and system for automatic control of a headlight of a vehicle by a mobile computing device. The mobile computing device receives vehicle related information and external information associated with the mobile computing device, where the mobile computing device is associated with an operator of the vehicle and is communicatively coupled with vehicle. Further, the mobile computing device computes an intensity and an orientation of a headlight of the vehicle based on one or more vehicle lighting patterns, where said vehicle lighting patterns are generated based on behavior of the headlight of the vehicle, which is operated by the operator, for a pre-defined duration in association with the vehicle related information and external information and provides computed intensity and orientation of the headlight of the vehicle to a lighting control module of the vehicle for automatic control of the headlight of the vehicle.
