Hi Michell, I'm glad to assist you. No. they are not reversible in the sense that they cannot be used in reverse. The design and structure are specifically intended for one-way operation to effectively clear or wipe the windshield of debris, rain, or snow. The orientation of the wiper blade is critical for it to perform its function effectively. For us to check carefully and be accurate on the part you need, please provide the complete details of your vehicle (year, make, model, submodel, and engine size).

Hi Blair, thank you for reaching out. As per the manufacturer, this item is incompatible with the 1997 BMW 840Ci. We will update this listing as soon as possible. Per checking with the Bosch brand, we don't have a matching wiper blade that fits your vehicle. Have a nice day.
