the 6" round LED light would replace the entire headlamp assembly. company says that the wide, medium and narrow lens options would not work -- the light pattern from the elliptical lens might. they haven't had anyone use them for motorcycle applications - and stated they are not DOT approved. they did, however, say that another company uses a modified-for-motorcycle version of their 2" spot/driving lights.
they're nice, cuz they're different -- but, i'll wait on them till after i find out about the fitment of the HIDs
