How to use 3 leg LED in a circuit?

A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device.
Bi-color LEDs contain two different LED emitters in one case. There are two types of these. One type consists of two dies connected to the same two leads antiparallel to each other. Current flow in one direction emits one color, and current in the opposite direction emits the other color. The other type consists of two dies with separate leads for both dies and another lead for common anode or cathode so that they can be controlled independently. The most common bi-color combination is red/traditional green, however, other available combinations include amber/traditional green, red/pure green, red/blue, and blue/pure green.

It is really very informative and Helpful. Utube really misses right and helpful videos. I must have tried couple of hours after which I could see this one. Long live friend.

[@SatyabratSwain1]

Thank you.

[@poccodroid9464]

I wanna have your help. Having Usha Iron. Was not picking heat. Repaired thermostate. Having a three pin LED indicator. It's connections i couldn't remember though i had taken a snap.
Now refitting that one wire of Indicator i just cannot understand, if can guide me. Have snap shots with me

[@user-jv4dc6uy8n]

wht happens when source power is switched off, will it drain battery via led red ??

[@SatyabratSwain1]

Yes
But It's take only 20mA current so battery drain will take a longer times.
