The Vemo Cornering Light Control Module (part number V20730178) is a small electronic device that is used to control the cornering lights on a vehicle. These lights are typically located on the front corners of the vehicle and are designed to illuminate the area to the side of the vehicle when turning. The module is responsible for activating the cornering lights when the vehicle is turning, and then turning them off once the turn is completed. This helps to improve visibility and safety while driving in low light or poor weather conditions. The Vemo Cornering Light Control Module is a reliable and essential component for any vehicle equipped with cornering lights.
