Introduction:
Turn Indicator Lights, also known as Directional Indicators, or Flashers, are an essential part of all automobiles.
They inform other road users, our intent, to turn left or right. 
There are several regulations and standards, that manufacturers must comply with, while designing and integrating Turn Lights on a vehicle.
In this video, we will learn, how to design a bike turning indicator circuit.
