Is your vehicle exhibiting brake lights staying on, sluggish brake light response when pressing the pedal, or a brake light fault on the instrument cluster? These symptoms usually indicate that the brake light switch internal contacts are worn or stuck, causing abnormal signal transmission. When functioning properly, this part detects the brake pedal position, precisely controlling brake light on/off while sending braking signals to the ECU to ensure driving safety. Compatible models include Peugeot 508L, DS7, and DF-Phenomenon i-Show GS MAX, OEM number 9813503180 (corresponding to 508L-DS7). Installation notes: first disconnect the battery negative terminal to avoid short circuits; after installation, manually test brake light response for synchronization and check pedal return to ensure smooth operation.
