The Auspicious S9 is a BA9s filament bulb used as the replacement lamp inside panel indicators, pilot lights and illuminated push buttons. The clear capsule glass lets the colour of the indicator lens show through properly, so one bulb type works behind red, green, amber or any other lens.

BA9s is a bayonet base. The two small pins on the side of the metal cap drop into the slots in the holder, then a quarter turn locks the bulb in place. It is the standard miniature base across most industrial indicator ranges, so this bulb fits a very wide spread of existing panel fittings without any adapter.

Five voltage options cover the usual control supplies: 6V, 12V and 30V for low voltage circuits, plus 130V and 220V where the indicator runs directly off the control or mains supply. Choose the variant that matches the voltage reaching the lamp holder, not the supply feeding the panel, since many indicators step the voltage down internally.

Filament bulbs remain the practical choice when you are maintaining older equipment, when the existing holder is wired for filament, or when a dimmable warm glow suits the application better than an LED. For new builds and for panels where lamp replacement is a recurring maintenance job, an LED indicator unit lasts far longer.

Common Applications

Replacement lamps for panel pilot lights and indicator units, illuminated push buttons that use a separate bulb, control panel status lamps on older machinery, machine console indicators, switchboard and distribution board signal lamps, and maintenance stock for any site still running filament based indication.

Related Indicators and Panel Components

Before ordering, confirm the voltage at the holder and the base type, since a BA9s bulb will not fit a screw or wedge base fitting.

If you are replacing bulbs repeatedly on the same panel, a sealed LED indicator usually ends that cycle. The 16mm LED indicators range covers red, green and amber in square and round heads on 24V, with 110V and 220V available, and the lamp is built into the unit so there is nothing to replace separately.

For the full selection of pilot lights, panel lamps and signal units in every size, browse the indicators collection. Where the indication sits inside the control itself, the 16mm push button range covers illuminated operators with the lamp behind the head.

This bulb belongs to the wider push buttons and indicators category, which carries the complete range of panel door components. For signalling that needs to be seen or heard across a workshop rather than read at the panel, see audible and visual signaling.

FAQ,s

What does BA9s mean on a filament bulb?

BA9s is the base type. The bulb has a 9mm bayonet cap with two pins that lock into the holder with a quarter turn. It is the standard miniature base used in most industrial indicator fittings.

Which voltage should I order?

Match the voltage present at the lamp holder, not the panel supply. Many indicator units drop the voltage internally, so check the holder or the original bulb before ordering.

Why is the glass clear and not coloured?

The colour comes from the indicator lens, not the bulb. A clear bulb lets the same part serve red, green, amber and other lenses, so you only stock one bulb type.

Can I fit an LED instead of this filament bulb?

Often yes, if a BA9s LED is available for the same voltage and the holder is compatible. Many panels are simpler to upgrade by replacing the whole indicator unit with a sealed LED type.

Does it fit screw base holders?

No. BA9s is a bayonet fitting only. Check the base on the bulb you are replacing before ordering.

Do you sell these in bulk?

Yes. Bulk quantities are held for maintenance and panel building. Contact us on +971 52 913 9543 for pricing.
