i were in same condition as per you cause of my eyesight problem. what i do is. Buy Philips Xtreme Vision H4 and H11 from @smartdevil_striker and make my Front windscreen sealant with NenoSkins Rain Kit bought from @ahmad_yar.
Now let me explain...
reason to make Sealant is at night in any condition Screen Remain Crystal Clear what ever Rain, Fog etc and Magiclly Screen Visibility Gets Better. This is my personal Experience. and i think every new car must Seal their WindScreen
Install H4 in Main head Lights and install H11 in Fog lights. now what to do is simple align Fog light to State Forward. beam should set to little up side. and see the Visibility Magic !!
i really Thanks to @smartdevil_striker and @ahmad_yar. those solved my Visibility issue and i'm their Satisfied customer and Recommend to every one
