The voltage of a bike light battery can vary, but for HID (High-Intensity Discharge) bike lights, it typically falls within a specific range.
According to the reference about Battery Packs for HID Bike Lights, the optimal voltage for firing an HID light is between 9V and 13.8V.
- If the battery voltage exceeds 13.8V, the bulb may experience premature failure.
- Therefore, selecting a battery within the 9V to 13.8V range is crucial for HID bike light systems.
