Strongly Introduction 12MM FL1P-12QJ-1 Terminal Indicator Light

What is a terminal indicator light?

Terminal indicator lights refer to devices that use light to monitor the operation or position state of circuits and electrical equipment.

The terminal indicator light is usually used to reflect the working state of the circuit (with or without electricity), the working state of the electrical equipment (running, down, or testing), and the position state (closed or disconnected).

Usually installed in the low-voltage distribution device of the screen, disk, table, cabinet on the panel, some low-voltage electrical equipment, instruments on the disk, or other prominent position.

Terminal indicator light reflecting the working state of the equipment. Usually, when the light is on, it means the equipment is live; when the light is off, it means the equipment is out of power.

Pilot lights and indicator lights vary primarily by the type of lamp used.

Incandescent lights emit light through a thin wire (filament) which becomes hot when electricity flows through it. It can operate on either AC or DC circuits; however, these devices are relatively inefficient, generate heat, and have shorter operating life spans than LED pilot lights.

LED lights are semiconductor light sources that require DC to operate.  If a DC circuit is not available, an LED driver can be used to supply the appropriate DC voltage and current.

They have the advantage of smaller size, longer lifetimes, and lower energy requirements than incandescent or fluorescent lights. Some LED lights can change color with the polarity of the current.

Fluorescent lights utilize fluorescent bulbs in which house electrodes at both ends of the tube and argon and mercury vapor throughout.

A phosphor coating on the inside of the tube emits light through the emission of ultraviolet light from the excitation and stabilization of mercury atoms.

Fluorescent bulbs tend to be more energy-efficient and longer-lasting than incandescent bulbs, but are less commonly used as indicators.

Halogen lights utilize a tungsten filament, inert gas, and a small amount of a halogen to emit light.

This combination allows for higher temperature filaments which can produce more light given the same energy (higher color temperature).

This favors their use as daytime indicators and warning lights which require brighter light.

Product Specifications

Important specifications for pilot lights and indicator lights include electrical requirements such as voltage, size, and color.

Based on the application, mounting style (panel, PC board) and terminal type (feed-through, wire leads, etc.) will also need to be considered.

To rate LEDs for use as pilot lights and terminal indicator lights, manufacturers state the luminous intensity in candelas, which is a function of the viewing angle.


Pilot and indicator lights are used as malfunction lights in automatic equipment, voice mail lights for telephones, condition panels, and dashboard lights for vehicles.

They can also be built into switches. Indicator lights are very versatile and are usually used in The coffee machine, The water heater, Water dispenser, Baked Fried furnace, Meat grinder, automation, Test equipment, Disinfection cabinet,

The dishwasher, Barbecues, Cleaning machine, Food machinery, The freezer, A blender, blender, The fault, Modified car, Shoe machine, Refrigeration equipment, Insulated rice stand, Cooking stove, Waterproof air case,

Induction cooker, Lampblack purifier, Cooking noodles barrels, Vending machines, Charging pile, The solar energy, Powerbox, The subway, The dashboard, wine, Audio equipment, Distribution box, Sound effector, The cinema,

Our company mainly produces and sells indicators for LED and neon bubbles.

How many ways to install the terminal indicator light?

There are two ways to install the terminal indicator light.

  1. Screw type, the terminal indicator light is installed on the panel, and then the nut is screwed on.
  2. Bayonet type, the terminal indicator light is directly stuck into the mounting hole, fast and convenient.

How many types of indicator lights?

There are too many types of the terminal indicator light, such as raised head, concave head, flat head, etc., you can also customize the style according to the individual needs, please check www.indicatorlight.com for details
