Apologize for dropping here by. Just wanna know that my dad has A4 with projectors on it. from dimmer bulbs in the past, projectors used to brighten them, which makes it more efficient.i have several Audi A6 projectors and i have no idea if they are even worth anything? doing a search in many forums, nobody really talks about Audi. if the projectors are not good, does anyone think the lenses are worth anything?
