You had better not expect to take rocks with this thing. The X2 light needs a rock guard that used to come with the unit. They stopped including this guard because the light melts it after extended rides. So, the solution is what? Ride without it. That's right, instead of fixing the problem they have decided to suggest you go without it. Anyway, thats a problem for those of us who ride trail & take rocks, eh? I must say that Motosport made a large error in not updating the photo of this product with one showing NO rock guard. It is even more irritating since Trail Tech stopped including the guards 3 years ago. Come on, Motosport. Bottom Line: Buy Something Else.
