I know im 6 years late haha, but Im just about to attempt this. Looks like I will need to use a 25mm drill bit to make a hole in the rear light unit cap, but should be pretty straight forward with the kit otherwise. Will reply with a picture when doneAny news on this? Would be interesting to see if anyone has managed to fit actual HIDs (with ballasts). This is something I'll be looking into doing in the future.
