I hope there is someone that can help me; I have a set of aftermarket angel eye headlights and for some reason one of them (offside) keeps misting up. I know the first thing someone will say is put the old ones back, even with the hot weather we have had I washed the car and it misted up again

Have I done something wrong when fitting them? And does anyone know how to stop this from happening?
All help will be grateful.
