Well said Anil.
Here is word from the book on use of indicators:-
'Indicator lights are amber in colour and can be located at the front, the rear and sometimes at the side of the car on both the left and right hand sides. You use your indicators to show an intended change of direction, whether turning left or right or moving out into traffic.
You only need to use your indicators if other road users (vehicles, cyclists or pedestrians) are visible.
Use them in good time, giving other road users plenty of time to react and adapt to your signal.
Once you have completed the manoeuvre make sure the indicator has cancelled otherwise you may confuse other road users.'
