For anyone sorting through signaling indicators operator controls, a pilot light is a small component with a real decision behind it. Do you replace one worn unit on an existing industrial panel, or do you buy a pack of compact LEDs for a new build? These two options take opposite approaches. One is a single heavy-duty pilot light, listed as used. The other is a set of new LED indicators at a much lower price.
Quick verdict
Choose the single Schneider Electric pilot light if you want a direct replacement from a named brand. Choose the 10-pack if you need several small indicators for a new panel or want spares on hand. The right pick comes down to your panel's opening size and how many indicators you actually need.
Price and condition at a glance
The price spread runs from $4.98 to $45.99, a difference of $41.01. That gap separates one used industrial pilot light from a bulk set of new LED indicators.
| Product | Price | Condition | Price Bar |
|---|---|---|---|
| Schneider Electric 9001KP35LGG31 30mm Green Pilot Light | $45.99 | Used | |
| 10Pcs 120V AC 10mm GREEN LED Pilot Lights | $4.98 | New |
Where each product wins
Schneider Electric 9001KP35LGG31 This one is about the heavy-duty industrial construction and the confirmation that the unit illuminates. The limitation is the used condition with possible cosmetic wear.
10Pcs 120V AC 10mm GREEN LED Pilot Lights This one is about quantity, new condition, and LED indication. You get the full lot in one purchase, which makes it easy to cover multiple small panels. The limitation is the lack of a brand name and the smaller panel cutout.
Product notes
Schneider Electric 9001KP35LGG31 30mm Green Standard Pilot Light

This pilot light from the 9001K Series uses a 30mm panel opening and screw-terminal connections. The voltage rating is 120V AC, and the lens is green. Each unit was individually powered and confirmed to illuminate, so the used status comes with functional confidence. The condition caveat is real: expect minor marks, discoloration, or signs of previous installation, and appearance varies between units. If your panel already has a 30mm cutout and you want a named industrial brand, this is the component to choose.
10Pcs 120V AC 10mm GREEN LED Indication Signal Pilot Lights

This 10-pack gives you new green LED indicators for a 10mm panel cutout. The LED construction offers a different indication technology from the standard Schneider unit, and the pack is well suited when you need multiple small lights for new panels or a stock of spares. The trade-off is the absence of a manufacturer name and the compact 10mm form factor, which is not sized for a 30mm opening. If your control panel uses smaller indicator openings, this lot covers several locations with one purchase.
Final choice by use case
- Single replacement for an existing industrial panel: The Schneider Electric 9001KP35LGG31 is the direct pick. Its screw terminals and tested illumination justify the $45.99 price.
- Multiple indicators for a new build or spares: The 10-pack of LED pilot lights is the better fit. At $4.98, you get the full set for less than the cost of the single Schneider.
- Brand recognition is important: Only the Schneider carries a named brand. If that matters for your project, accept the higher price.
