The product is a genuine OEM 2016-2017 Subaru Legacy Outback blind spot radar sensor with the part numbers 87611 AL01A and A2C75133701. It is designed as a direct fit and is located on the rear of the vehicle. This radar sensor is an essential component of the advanced driver assistance systems in these Subaru models, providing accurate detection and information for the vehicle's. blind spots to enhance safety and visibility while driving. Only one of my sensors were bad but the dealership replaced both. I am including the defective part (marked with an X) in the box in case you need an extra bracket.
