hi guys.i have an audi a3 1.8t quattro sport(180 bhp) 2002.love the car to bits but i do found the headlights very dim.i have upgraded the bulbs to the brightest ones that halfords do (120% brighter) than standard apparently.sadly not much better than the osram ones i had before.looking at the lenses the look slightly cloudy.do i need to replace them?.the car has covered 105,000 miles,any ideas ,thanks
