Setup, Compatibility & Care
Compatibility Check: Before purchasing, meticulously verify that this bulb's specifications (BAY9s socket, 24V, 21W) and the vehicle fitment list (Scania G I/II, Iveco Zeta, Mercedes-Benz Actros MP4/MP5, Antos, Arocs, Volvo FM/FMX II, MAN TGS I/TGX I) match your specific vehicle's requirements. Check your vehicle's manual or existing bulb for confirmation.
Installation: Ensure the vehicle's ignition is off and the lighting system is cool before attempting replacement. Carefully remove the old bulb from its socket, paying attention to its orientation. Insert the new Hella bulb, ensuring the BAY9s base seats correctly and securely. Reassemble the light housing.
Care: This is a consumable part. Avoid touching the glass surface of the bulb with bare fingers, as oils can reduce its lifespan. Use a clean cloth or glove. Regular checks of indicator function are recommended as part of routine vehicle maintenance.
