These neon indicator lamps are a simple and reliable way to add a power-on indicator to your electrical projects. Each lamp comes with a built-in resistor, making them ready to connect directly to a 220V AC mains supply. This pack of 20 red glow lamps is a practical solution for DIY enthusiasts and repair professionals.

Each lamp is small and easy to install, fitting into a standard 4.2 cm by 0.5 cm panel hole. The bright red glow provides a clear visual confirmation that power is present. The included resistor ensures safe and consistent operation, simplifying your wiring process.

Built from durable plastic and metal, these indicator lamps are designed for long-term use. They are a cost-effective and efficient way to add status indication to switchboards, power strips, appliances, and custom electronic enclosures.

Usage Scenario

Mark was wiring a new power supply for his home workbench. He needed a simple way to know when the unit was live. He drilled a small hole in the front panel, pushed one of these neon lamps into place, and connected the two wires to the 220V input. The instant he powered up the supply, the lamp glowed a steady red. The installation took less than a minute, and the indicator gave him a clear, safe visual cue every time he used his bench.

Micro Comparison

These lamps are a direct and cost-effective alternative to larger panel-mount LEDs that often require complex current-limiting circuits. The built-in resistor eliminates extra components, making installation faster and cleaner. For basic power-on indication at 220V AC, this neon lamp is a simpler and more durable choice.

Questions and Answers

Question: Can I use these lamps on a 110V circuit?

Answer: These lamps are specifically designed for 220V AC mains. Using them on a lower voltage may result in a very dim or no light output.

Question: Do I need to add an external resistor?

Answer: No. Each lamp comes with a built-in resistor, so you can connect them directly to a 220V AC supply.

Question: How do I mount these lamps into a panel?

Answer: You typically drill a 4.2 mm hole, insert the lamp from the front, and secure it with the included nut or by using a small retaining clip.

Question: What is the wire length on each lamp?

Answer: The wire leads are approximately 5 cm / 2.0 in long, which is enough for most panel wiring connections.

Question: Are these lamps suitable for outdoor use?

Answer: They are not weatherproof. They are designed for indoor use inside enclosures or panels where they are protected from moisture.
