Impulse must be installed to the interior of the rear window. It is designed to work with all passenger vehicles with a fixed or hinged rear window. However, it does not work on convertibles nor vehicles with rear windows that slide down, as the product may not have adequate clearance when the rear window is lowered. Window tinting darker than 35% VLT will have a noticeable impact on output brightness.
