Product Overview

This high-quality Original Front Stop Brake Light Switch is designed to meet or exceed factory performance standards and is suitable for Yamaha NMAX 125 (2021-2024) models.

The front stop brake light switch is mounted on the front brake lever assembly and signals the brake light circuit to illuminate when the lever is applied, providing a vital warning to following road users. A failed or sticking switch can prevent the brake light from responding to front lever inputs, creating a road safety hazard, or cause it to illuminate permanently, masking the braking action from drivers behind and placing excessive drain on the battery. This original replacement restores the original front brake light switch function, ensuring seamless, secure, and reliable operation of your NMAX 125.

Complete Part Guide

Not all safety issues are obvious. The original Yamaha NMAX125 Front Stop Brake Light Switch (B6H-H3980-00) for 2021–2024 models works quietly in the background, ensuring your brake light activates every time you slow down. When it starts to fail, the risk isn’t always visible, but it’s there. Designed to Yamaha’s original specifications, it provides accurate activation, proper fitment, and dependable performance. Available now from Part Hive's London hub, with fast same-day UK dispatch on orders before 1 PM.

What we look for is consistency. If the brake light works one time but not the next, that’s already a failure in our book. These switches wear unevenly, and the problem comes and goes at first, so we test it repeatedly to catch that pattern. Once replaced with the correct original front stop brake light switch, the activation becomes consistent again, exactly how it should be on your NMAX-125.
