What This Brake Light Switch Does

This switch is located directly on the front right brake master cylinder. When you pull the brake lever:

• The switch activates
• Your rear brake light illuminates
• Other road users are alerted that you’re braking

If your brake light has stopped working when using the front brake, this small switch is often the cause — making this the perfect low‑cost replacement part.

• Directly fits the front right brake master cylinder
• Activates the rear brake light when the lever is pulled
• Helps maintain road‑legal safety compliance
• Suitable for a wide range of motorcycles, scooters, mopeds & commuter bikes

If your existing switch is mounted on the front right brake master cylinder and uses a simple push‑button contact layout, this is likely a direct replacement.

Why This Switch Is Important

A working brake light is a legal requirement in the UK, Ireland, and across the EU. Without a functioning front brake light switch:

• Your brake light may not illuminate when using the front brake
• Cars behind you may not notice you’re stopping
• Your motorcycle will fail an MOT test
• It becomes unsafe to ride at night or in traffic

Replacing this switch ensures safe braking communication with other road users.
