This brake light switch is designed for Peugeot 207 Sedan 2008-2014 all variants; matches OEM interface and can be installed directly. It controls brake light on/off and sends brake signal to ECU, affecting transmission shift logic and cruise control. Replacement difficulty low; about 20-30 minutes; remove undertray and unplug connectors. If brake lights stay on or do not light, or the instrument panel shows "Brake light fault" or cruise control cannot be set, switch needs replacement.
