Today one of my friend who is also a mechanic was invited on my house on dinner. Discussed the above mentioned problem with him. He started checking with a tester that the head beams were getting the current or not. Secondly he opened the on / off knob for lights that was also passing current. Then he opened the steering wheel and removed the stick meant for the wipers/ low & high beam. He found that to be the main culprit. So we both went to the junk market and purchased the whole of the stick along with its connections for 30$. Not bad at all. The whole problem was solved there and then.
This might help for those who are moving with the same problem
