Most likely cause
BasicBlown bulb
The most frequent and simplest cause: a broken filament or blackened glass. A single light affected = almost always the bulb. Replace with a bulb of the same type and rating (base/wattage engraved or in the manual). Don't touch halogen glass with bare hands. 🟢 A few minutes to replace. This tool helps you understand what's going on -- it doesn't replace a certified mechanic.
How to make the repair yourself
🟢 Within reach of any rider: no advanced mechanical skill or specialised tooling needed.
- Identify the affected light and get to the bulb (rear headlight cover, removing the light unit, or a hatch depending on the model).
- Remove the bulb and check: broken filament or blackened glass = dead.
- Fit a new bulb of identical type, base and wattage. For a halogen, handle the glass with a clean cloth (grease burns it out).
- Test before refitting everything; also check the headlight beam alignment.
⚠️ This tool helps you understand what's going on with your motorcycle; it doesn't replace the inspection or judgment of a certified mechanic. If in persistent doubt, if a safety-critical part is involved (braking, steering, bearings, transmission), or if the problem keeps recurring, have the diagnosis confirmed at a workshop before doing any work.
