These neon indicator light bulbs come in a convenient 10-pack with two popular sizes and three bright color options. Designed for 220V circuits, each bulb includes a built-in resistor for simple and reliable installation as a power-on indicator in various electronic devices and appliances.

Each bulb provides a clear, visible glow to show when equipment is powered on. The compact 4x10mm and 5x13mm sizes fit standard indicator light holders, making them a practical replacement or addition for DIY electronics, power strips, switches, and control panels.

The package includes 10 bulbs in your choice of red, blue, or green light. The built-in resistor simplifies wiring because you do not need to add an external component. This design helps ensure consistent performance and a long service life for your indicator light needs.

Key Features and Benefits

- Built-in resistor simplifies installation and ensures safe 220V operation

• Two compact sizes (4x10mm and 5x13mm) fit standard indicator light holders

• Choice of red, blue, or green light for clear visual status indication

• 10-pack value provides spare bulbs for multiple projects or replacements

• Low power consumption and long lifespan for continuous use

Who Is This For

- DIY electronics enthusiasts building or repairing power supplies and devices

• Technicians needing replacement indicator lights for appliances and equipment

• Hobbyists adding power-on status lights to custom switch panels or projects

• Anyone maintaining or upgrading power strips, surge protectors, or extension cords

Usage Scenario

Mark was repairing an old power strip that had a dead indicator light. He ordered this 10-pack of neon bulbs. He chose a red bulb for the power strip, soldered it into the holder, and the light worked perfectly. Now he has nine spare bulbs for future projects, including adding a blue indicator to his custom computer desk switch panel.

Micro Comparison

Unlike standard LED indicators that require current-limiting resistors and careful polarity, these neon bulbs work directly with 220V AC circuits thanks to their built-in resistor. They are also more durable than older glass fuse-style indicators and provide a consistent warm glow that is easy to see from a distance.

Why You Will Love It

You will appreciate the convenience of having 10 bulbs ready for multiple projects. The built-in resistor saves wiring time and reduces the risk of connection errors. Seeing your equipment power on with a clear, bright indicator gives you confidence that everything is working correctly.

Questions and Answers

Question: Can I use these bulbs with 110V circuits?

Answer: These bulbs are designed for 220V circuits. Using them with 110V will result in a much dimmer glow or no light at all.

Question: Do I need to add a resistor when installing these bulbs?

Answer: No, each bulb has a built-in resistor. You can connect it directly to the 220V power source.

Question: What is the difference between the 4x10mm and 5x13mm sizes?

Answer: The 4x10mm bulb is slightly smaller and fits tighter spaces. The 5x13mm bulb is larger and may be easier to handle. Both work the same way.

Question: How long do these neon bulbs typically last?

Answer: Neon bulbs have a long lifespan, often exceeding 20,000 hours of continuous use under normal conditions.

Question: Are these bulbs polarity sensitive?

Answer: No, neon bulbs are not polarity sensitive. They work with AC power in either orientation.
