Nissan Micra K12 - Micra k12- 2003 Head Light Problem - bogzy

Hi, I have a 2003 Micra k12, and have an issue with the head light. The dip is working fine but the head lights wont turn on. i took it to a mechanic and he changed the plastic sockets holding the bulbs saying that they were not good, the lights were working @ the mechanics place but when i tried them later on , they were not working ! the head light indicator(blue light in the dash board) works fine but the lights won't come on. please help me on this.

Regards
