Two Color LED Indicator Light: Bulk Production of 6mm 12V Solar PV Common Anode Red Green

6mm two color LED indicator light is a small LED indicator light that is used to display the status of devices. It usually consists of a metal or plastic housing and an internal circuit.

The two color indicator light with a metal housing is also called an explosion-proof indicator light. This indicator light can display two different colors, usually red and green, but it can also be other colors, such as blue and yellow.

In the circuit, the two color indicator light usually uses three pins, one of which is common anode or common cathode, and the other two pins are used to control the red and green LEDs respectively.

Due to its small size and two color design, 6mm two color LED indicator light is widely used in compact electronic devices, such as medical devices, electronic instruments, robots and automotive electronic systems.

At the same time, due to its waterproof performance, they are also suitable for outdoor applications, such as car lights, boats and industrial equipment.

12MM 12V Metal Red LED Indicator Light

Features of 6mm Two Color LED Indicator Light

6mm metal two color LED indicator light is rarely produced by indicator light factories due to its small size and the need for extra pins for the two color LED.

However, FILN indicator light factory specially designed a 3MM two color 3-pin LED with a plastic cap design to meet the market demand. The plastic cap can both focus the light and have a waterproof effect.

The 6mm 12V metal two color LED indicator light is fully filled with glue inside, so it has a waterproof rating of IP67. This red green LED indicator light is specially designed for energy storage batteries and can provide different voltages such as 3V, 6V, 12V, 24V, 110V, 220V.
