I currently have the 2xcite halo lights fitted to the z4 which has the motors in them. These replaced a set of xenon headlights as they started to let moisture in and it ruined the inners. I had these fitted over 10 years ago by a local garage. They did have a few issues with fitting them as it wasnt quite a plug and play due to the car not replacing the standard Halogens. Im now having issues with the Halos and am thinking of just getting a set of standard Halogens off Ebay and fitting them as the xennons are quite rare and more expensive. If I did go down this route is it a straight forward swap? Has anyone done this? Or am I just better off getting another set of Halo's?
