OK, I may have missed something in the errata, but the description for Photo-visors' says that they grant you the trait 'Dark Sight', then refers you to page 325. Except there's nothing on that page except background stuff. Am I missing something, or is this actually a faulty equipment and rule description thats gone unnoticed?

The page reference should be 329. That's where the Dark Sight trait is listed.

Ah, excellent, thanks
