5-Pack B9/E10 Screw-Mount Signal Lamp Bulbs – 24V 2W, Glass Bayonet Base, Warm Yellow Indicator Light For Panels & Instruments

About This Product

If you've got an old control panel, test equipment, or instrument that needs a replacement indicator light, these B9/E10 bulbs are exactly what you're after.

This pack gives you 5 bulbs with a bayonet base (that's the B9 style) and they come rated at 24V and 2W – a common spec for many industrial and DIY setups.
The glass construction is standard and reliable, and they put out a warm yellow glow that's easy on the eyes.

These are small – about 26mm tall with a 9mm diameter – so they fit snugly into tight spaces.

They're also available in other voltages like 6.

3V, 12V, 30V, 36V, and 48V, so if your project needs a different rating, you've got options.

The threaded/screw-mount versions are also available for those who prefer that style.

Perfect for replacing burned-out indicator lights on machinery, audio gear, or even vintage electronics.

They're simple, they work, and they're cheap enough to keep spares on hand.
Just match your voltage and you're good to go.
