How to Replace a Brake Light Switch on a BMW F750GS

Replacing a broken brake light switch can seem daunting, but with the right guidance, it’s a manageable task. This guide will walk you through replacing the brake light switch on a 2019 BMW F750GS, offering valuable insights learned from a real-world experience.

Understanding the Brake Light Switch Issue

The brake light switch on a BMW F750GS, like many motorcycles, is susceptible to damage, especially during off-road riding. Mud, dirt, and debris can accumulate around the switch, leading to breakage. In this specific instance, off-roading through deep ruts resulted in a broken switch and a bent brake pedal. This highlights the vulnerability of this component and the need for careful consideration during off-road adventures.

Replacing the Switch: A Step-by-Step Guide (Based on Experience)

While a detailed step-by-step replacement procedure requires a dedicated guide, this section focuses on a crucial aspect of the process: the orientation of the metal plate on the brake light switch. This seemingly minor detail can cause significant confusion during installation.

The BMW F750GS uses a brake light switch that can be mounted in multiple models. This switch features a small metal plate that can be positioned on either the front or the back. Crucially, on a 2019 F750GS, this metal plate should point towards the front wheel when the switch is in the open (unpressed) position.

If you’re replacing the switch, carefully examine the new part. If the metal plate is not oriented correctly, you’ll need to remove it and reposition it on the opposite side. This ensures proper functionality and prevents recurring issues. This step required confirmation from other F750GS owners due to the original switch being damaged beyond recognition.

Protecting the Brake Light Switch

Given the vulnerable location of the brake light switch, protecting it from damage is a valid concern. Currently, there aren’t readily available aftermarket solutions for shielding the switch. The positioning of the switch makes it difficult to design effective protection without interfering with the brake pedal operation.

Lessons Learned: Off-Roading and Repairs

This experience reinforces a fundamental truth about off-roading: breakage is inevitable. Regardless of the vehicle, pushing its limits off-road will likely result in some damage. Accepting this reality helps prepare for potential repairs and reinforces the importance of regular maintenance and inspections. While a broken brake light switch might seem like a minor setback, it underscores the need for preparedness and understanding the intricacies of your motorcycle. Knowing how to address such issues can save you time and frustration on the trails.
