AKL means Adaptive bi-xenons. To my understanding, all US cars have adaptive bi-xenon standard (therefore AKL).
However, in Europe they have an option to have bi-xenon without the adaptive function so that is why there are 2 versions of the headlight.
I am interested in this as well but still haven't had any confirmation from those who's done it what parts are actually necessary and what was done, so I am holding off.
Flpnout, if you do get a chance to get it and it works, please do post back with results and maybe a DIY
By the way, good to see you back on here!
