Rear hydraulic brake light switch

Precise activation, 12V compatible, for all M10 banjo screw

Enhance your motorcycle’s safety and reliability with this rear hydraulic brake light switch. Designed to install directly on the hydraulic braking circuit, it triggers the brake light as soon as you press the brake pedal, with no mechanical parts prone to quick wear. It’s the ideal solution for stock bikes, café racer, scrambler or bobber builds, and any setup requiring a robust, precise rear brake switch.

Thanks to its 12V compatibility and universal design for hydraulic braking systems, this switch fits a wide range of motorcycles. Fluid pressure activation ensures crisp brake light illumination, even in tough conditions. Waterproof and reliable, it withstands exposure to brake fluid and the weather, while delivering consistent response every time.

Whether you’re replacing a tired switch or upgrading your wiring harness, this hydraulic switch provides a clean, efficient, and durable solution. It connects easily to your motorcycle’s 12V electrical system and ensures compliant, visible rear signaling for more confident riding.

Technical specifications:

• 🛠 Type: rear hydraulic brake light switch for braking circuit

• ⚡ Voltage: 12V DC (standard motorcycle electrical system)

• 🔌 Connection: 2 wires for easy harness integration

• 💧 Sealing: designed to withstand brake fluid and splashes

• 📏 Dimensions: compact form for a discreet install

• 🧩 Mounting: install on the rear hydraulic braking circuit

• 🧪 Durability: stable, long-lasting triggering, with no exposed mechanical parts

Advantages over stock:

✔ Precise brake light activation with every press
✔ Less wear risk than a mechanical switch
✔ Waterproof and tough for real-world conditions (rain, dust, brake fluid)
✔ Simple 12V integration into most motorcycle harnesses
✔ Compact size, ideal for builds and restorations

Why upgrade the stock part?

Many stock systems rely on mechanical switchgear sensitive to wear, oxidation, or poor adjustment. Over the miles, the brake light can become irregular, delayed, or intermittent, which harms safety and visibility for the rider. A hydraulic switch eliminates extra levers and springs and reacts directly to braking pressure.

• Failure or sticking of the mechanical switch

• Tricky adjustment, wear of springs and levers

• Late or random brake light activation

• Exposure to moisture and dirt causing bad contacts

This hydraulic switch solves these issues by triggering the brake light via hydraulic pressure, for an immediate, reliable, and consistent response. Its sealing and simple design reduce maintenance and increase durability, while enhancing braking safety.

Ideal uses:

• Replacing a faulty rear brake light switch

• Café racer, scrambler, bobber or custom builds

• Restoring older motorcycles equipped with hydraulic brakes

• Improving rear signaling reliability on urban and suburban roads

• Simple integration into a 12V harness for DIY projects
