Strange, I had a gen1 tundra just short of 300k miles, and never received any headlight damage not even a scratch. The lens did become oxidized badly over time that I had to keep restoring them. Question is, do they prevent that? This stuff pictured looks like it would cut back on the lighting your headlight projects....not good imo. I don't even know if they're legal for use in our state. State is pretty adamant whats legal for use on a vehicle like type of lens, and window tint.
