I Think You can download it and plae
Installation:
1. Drag "The Lights" folder from the .zip archive to Amnesia: Rebirth "mods" folder.
2. Open custom story from the main menu in A:R.
3. Choose language - settings->game (English or Russian). There I also recommend turning off the Hints.
(Русский язык в настройках, рекомендую отключить подсказки в том же окне.)
