Restore your nighttime visibility with the Genuine OEM Headlight Bulb. Specifically engineered as the factory-standard replacement for many 139QMB series scooters, this bulb delivers a crisp, reliable beam for safe urban commuting. Whether you are replacing a burnt-out filament or performing a seasonal safety check, this dual-filament bulb provides the precise 35/35W output required by your scooter's electrical system.
This bulb is the standard factory replacement for the Chicago Scooter Company lineup and many QMB139 powered vehicles: CHECK to make sure base is BA20D Style
Mechanic's Note: Headlight bulbs are often the first casualty of a failing voltage regulator. Installation Tip: Never touch the glass of the new bulb with your bare fingers; skin oils can cause "hot spots" that lead to premature bulb failure. Pro Tip: If your bulbs are constantly blowing, check your Voltage Regulator to ensure your system isn't overcharging!
