The Fiat 500 has been in continuous production since 2007, becoming one of Europe's most recognisable city cars. The rear window is toughened glass and typically features integrated brake-light circuitry, a high-level stop lamp wired into the glass itself.
From 2020 onwards, newer 500 models introduced the Co-Driver ADAS suite, which uses forward-facing cameras for traffic sign detection and driver assistance. While the rear window itself doesn't carry a camera, replacement on these variants involves parts-check verification to ensure the brake-light wiring pattern matches your vehicle exactly.
Some 500C cabriolet variants feature an integrated window antenna with an amplifier module bonded into the rear glass — this must be handled carefully during replacement to avoid damaging the antenna circuit.
