Sorry I can't comment directly if the lenses will fit. But, I can tell you that if you want the performance of the genuine European lights, you need both the E lenses and the reflector unit (the rear housing). The DOT unit has different shaped reflectors. Also, the lights I tried from FCP were a Taiwanese manufacture and seemed rather compromised. I returned them and had a friend bring me some genuine Hella units from Sweden. Check the archives from about Oct. 2004 for more information.
