Abstract
An automotive vehicle having an aperture in the vehicle body in which a glazing, comprising a switchable film laminated between at least two plies of an interlayer material is fitted is disclosed. The plies of interlayer material are laminated between a first ply of glazing material, preferably glass,facing out of the vehicle and a second ply of glazing material, preferably glass, facing into the vehicle. The switchable film comprises first and second electrodes, both in electrical connection with a power supply. The first electrode is capacitively connected to electrical ground on the vehicle body.
