this is one real bug bear for me, having had OEM xenons on near enough all my previous cars, and having bought a 1 series sport that doesnt have them is really starting to rile me now, not only do they look gash, I find they give generally poor lighting also, in comparison to other halogen lights especially when on motorways or country lanes etc. As upgrading to the OEM angel eye/bi xenon is just pretty much out of the question due to price, I was wondering if this could be the way forward and anyone had a crack at a retrofit project, or like me considering the option, I may become the guinea pig if not as i really do want to do something with my lights, I have an old Audi A3 headlight sat in my garage doing nothing and some old HID kit stuff laying about, so am going to order a set of these and have a trial run: ive been doing some research and it looked pretty straight forward to do to be fair, my only concern is not knowing how much "butchering so to speak may be involved which is why once ive got hold of my kit im going to trial it on the A3 headlight, there are loads and loads of examples of all types of cars on this website i came across but here is a good one of an older style 1 series, and hes done a pretty daymn good job, seen as there are no aftermarket style projector lights on for our f20, its either OEM or lump it, and i think this could be worth a punt. http://www.hidplanet.com/forums/showthread.php?52722-BMW-128i-FX-R-and-Some-LED-s thoughts?
