1st check the condition of reflector, it shud be shiny like chrome and not like aluminium...
if you have used HID in past, then its almost sure that reflector is gone and beyond repair...
if reflector issue, then you need a new pair of headlights...must be original one....or you can also try to find a good condition reflector from used part market and get it replaced in ur headlights...not a very difficult job...
also check the headlight cover...if it is oxidised, then do some cleaning make it transparent...
install philip rally tubes H4 90/100watts...it is more thn sufficient for city and hi way used.
also install ready made relay kit in the wiring to safeguard the headlight switch from heating up..
