I have broken my fogs 3 times in the first year. Once, a chunk of particleboard actually rocketed the whole housing inside the bumper, later both were hit by rocks and cracked the glass. I simply fixed the housing with some gorilla glue, and then coated them with rubberized vibration dampening and undercoating, and then covered the cracked lenses with yellow laminx and replaced the one broken light bulb. They have been better than ever since I laminXed it. BTW the car has over 30k miles, and its just over a year old.
And you can't really see the billet grilles at all since they are black. But they DO save your AC condenser, which is much more important than the fog lamps
