you cant just buy the lens...everywhere sells the whole headlight assembly unless you got a friend who has an extra pair just lying around. ive seen bad aftermarket headlights on ebay and they get water in them and look crappy but me and a friend but some black halos on a rsx and its been 2 years and they still look in amazing condition. we took a risk knowing he might get water inside the headlights but that didnt happen.
