Headed To Gunnison

That had to be a pretty large object to break a 2” diameter piece of pretty thick plastic. Likely the light lens itself would have not survived had you not been riding with the cover lens.

I think it all had to do with pressure. If the small rock that likely caused that had a point that contacted the lens directly, then the pressure seen at the point would easily cause that failure. Like you said, good thing it was the lens cover.
