I bought these for an Artic Cat 500 and they are like night and day improvement over OEM lights. I ride in a heavily wooded area and these things light up the night like nobodys business. They are a little on the expensive side, but I highly recommend them if you want to really see trails at night.
This light is pretty cool and works awesome definetly a lot brighter than the stock ones. the only thing that i didnt like was that it was kind of expensive and i just ordered one to start out with because i thought they came in a pair so it does get somewhat expensive when you get two but if you dont mind spending the money this is a good way to make your quad pretty cool and help out with the night rides.
