Of course, it always depends on the mass and velocity of the rock. But it seemed pretty tough to me, and certainly enough for the kind of gravel typically thrown up by something ahead of you on the highway. I wouldn't want to be hit at all by anything that would have broken the lens through the film.
I was just thinking about the time in my van when on an interstate highway and a truck ahead of me kicked up a rock that caused a big enough gash in my windshield that it had to be replaced. To me, if I had a headlight protector, it would have to be tough enough to withstand something like that. I know 3M wouldn't have helped in that situation. I have used it extensively for scuff protection on the tank and saddlebag areas, etc but that is different than trying to protect from a hit from an airborne stone. Couldn't hurt, I guess and might help in some situations.
I guess I have been lucky in about 45 years of riding, I have never had a headlight damaged. I guess I'll just keep on keepin' on and if a stone flies up and damages my headlight I'll do the same as when the stone damaged my van's windshield, let my comprehensive insurance take care of it.
Now that I opened my big mouth about that, I'll probably be the first Super Tenere owner in the USA to get a damaged headlight. :'(
