Hi
I have BI-LED projector upgrade kit for sale, I bought it to change it on my A6 4f which is very easy to do but changed my mind as might be leaving UK soon.
Kit is listed on Ebay: https://www.ebay.co.uk/itm/202350968091
Perfect upgrade if your b-xenon is dying 😄
Happy to answer any questions.
Regards
