Volkswagen Golf Gti 1J Sharan 7M Polo 6N Brake Light Switch Sensor 191945515B

Volkswagen Golf Gti 1J Sharan 7M Polo 6N Brake Light Switch Sensor is an original component from the Pedals, pedal pads and footrests group, responsible for the precise activation of brake lights. It is a practical solution for users who want to restore the proper operation of the brake light system in their Volkswagen while maintaining factory operating logic and consistency with the vehicle's electrical installation.

Function and application of the brake light switch

The presented switch operates in the brake pedal assembly area, where it is responsible for generating a signal when the pedal is pressed. A properly functioning component ensures:

• instant activation of brake lights during braking,
• a clear signal for drivers behind you,
• compatibility with vehicle systems that utilize braking information. Thanks to the preservation of the factory design, the switch works with the original electrical harness, which promotes stable system operation and reduces the risk of errors resulting from improper fitment.

Construction and fitment to the pedal system

The component was designed by Volkswagen for installation in specific models, such as the Golf GTI 1J generation, Sharan 7M, or Polo 6N, while maintaining the correct geometry relative to the brake pedal. This includes:

• a housing adapted for seating in the pedal bracket,
• an operating mechanism that reacts to pedal movement within a specific range,
• an electrical connector matched to the vehicle's factory harness. This solution allows for installation without structural modifications, which is particularly important when servicing the braking system and maintaining compliance with the manufacturer's documentation.

Benefits of using an original switch

Using an original brake light switch instead of a worn or damaged component allows for maintaining the consistency of the system's operating parameters. Key advantages include:

• stable brake system operation – predictable reaction to pressing the brake pedal,
• preservation of factory electrical characteristics,
• reduction of the risk of improper light operation (constant illumination, no reaction, flickering),
• easier diagnostics during future inspections or repairs. For users who prioritize compliance with service documentation, choosing such a component is a practical way to maintain the proper operation of the braking system in the part responsible for signaling.

Product characteristics and condition

The offered switch belongs to the Pedals, pedal pads and footrests group, which means it operates directly in the brake control zone. The product is in used condition, which in practice means it comes from disassembly, and its construction retains the features typical of original components factory-installed in Volkswagen vehicles. Before installation, it is recommended to perform a standard check of the correct seating in the bracket and the security of the electrical connection to fully utilize the potential of this component in daily operation.

Expanding service within the brake control system

If you are planning a comprehensive repair or upgrade of the brake control zone in your Volkswagen and need other elements from the same group, such as additional switches, pedal mounting elements, or supplementary footrests, check the available parts in the Volkswagen Pedals, pedal pads and footrests category. If you want to better evaluate when using a used brake light switch is economically and technically justified, it is worth reading the guide on selecting used components – you will find it in the article Operational faults vs. costs: how to repair a car using used auto parts?.
