Standard aluminum pop-rivets that you can get at any hardware or big box store.
Be sure to put some sealant in the holes before inserting and squeezing the rivets to seal them well against water intrusion. You won't need Snap Caps because they are riveted inside under the lens.
If you go to a hardware store, True Value, Ace, Do-it-best types of chains that have all those bins of individually sold
nuts and bolts you should be able to find in that section of the store some 1/8" Dia x 1/2" L stainless steel pop rivets with a solid pin. I can pull that size of stainless rivet with a hand operated rivet puller. The stainless rivets have a greater strength than the aluminum rivets. You will also find in that by-the-piece bin area the small rubber washers to use with pull rivets. I have been getting mine at my local Do-It-Best hardware store.
