I seem to be here more and more regularly lately!!
i have a N Reg 1996 Mondeo (petrol). recently I have noticed a dark 'shadow' through the middle of my headlights - this shadow runs from top to bottom and is dead centre of the actual headlight itself. I have tried cleaning the glass and changing the bulbs but still this shadow persists.
Not sure what else to look for - any ideas/help would be much apprecited.
