FAQs

What vehicles is this Hella bulb compatible with?

This bulb is compatible with specific models including Scania G I (2012-2019), G II (2017 on), Iveco Zeta (1979-1991), Mercedes-Benz ACTROS MP4 / MP5, ANTOS, AROCS, Volvo FM, FM II, FMX II, and MAN TGS I, TGX I. Always verify your vehicle's specifications.

What is the voltage and wattage of this bulb?

The bulb operates at 24 volts and has a rated power of 21 watts.

What is the socket type for this bulb?

The socket type is BAY9s.

Can I use this bulb in a vehicle with LED daytime running lights?

No, this bulb is specified for vehicles *without* daytime running light (LED) systems. Using it in such a vehicle may cause compatibility issues.

Where is this bulb fitted on the vehicle?

It can be fitted to the front, rear, and lateral positions of the vehicle's indicator system.

Is this bulb road legal?

Yes, the bulb is ECE approved, meaning it meets European standards for road safety and legality.

How do I avoid damaging the bulb during installation?

Always ensure the power is off and the bulb is cool. Avoid touching the glass with bare hands; use a clean cloth or gloves to prevent oil contamination, which can shorten the bulb's life.

Troubleshooting

Bulb does not light up.

Ensure the bulb is correctly seated in the socket. Check the vehicle's fuse for the indicator circuit. Verify the vehicle's electrical system is receiving 24V power and that the bulb is compatible with the vehicle's non-LED daytime running light configuration.

Indicator flashes too quickly or too slowly.

This bulb is typically designed for standard flashing rates. If the speed is incorrect, it may indicate an issue with the vehicle's flasher unit or a wiring problem, rather than the bulb itself. Consult a qualified technician.

Bulb fails prematurely.

Ensure the bulb is the correct type (24V) for the vehicle and that there are no voltage fluctuations or short circuits in the vehicle's wiring. Avoid touching the glass during installation. Vibrations from rough roads can also affect bulb life; ensure secure mounting.

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.
