Turns out I was in drive, and rolled forward a few inches when I took my foot off the brake. I heard a crunch which was the shattering of one of my PIAA light lenses, and the crumpling of the PIAA logo and covering over the other.
I have looked online and seen brief references to PIAA lens replacements, but I have not found (yet) any areas in Victoria that supply PIAA parts - assuming I can get just the lens and cover for my 520 lights. (I am assuming that they are 520 fogs, I don't actually know.)
On the upside my Princess Auto $12 6" driving lights have arrived, and they look like they will mount to the stock bull bar just fine. There are some points on them where I will have to seal them against water, and I can see how the reflector backing is not as good as my PIAA lights (like jfarsang and others noted before). Still, I can afford to crush $12 lights and not the PIAA ones!

****EDIT****
After doing some digging I found a list of PIAA dealers in BC, including Victoria. So, I will try contacting those guys to see if they can identify the model of PIAA lights I have and if replacement lenses are available.
