For more and more vehicles, a rain or light sensor is already part of the standard equipment. During the windshield, the sensor optical unit is also often replaced, although this is not necessary. Our special adhesive pads, made of a completely transparent, self-adhesive material, allow the optical unit to be reused. How to proceed: First, carefully remove the optical unit from the glass using an installation rod or sensor removal tool. Since most optical units are made of plastic, they must not have a use with solvent-based cleaners. It is best to peel off the remaining glue with your fingers. For final cleaning, use a cleaner that evaporates without residue and does not corrode the plastic. Now first glue the adhesive pad to the optical unit and then the entire part to the windshield.
