well Coure meters tend to get dust stuck in them and because of that lights go dim in night.
Firstly i would recomend go to your local mkt electronic's and get the meter cleaned up specially bulbs.
hopefully it should help and wont charge you much max should be between 200Rs to400.
If that dosent help then just change the meter bulbs to stronger one's and your total cost should not be mpre than 500Rs
