Where is Lucky's Fortnite lighthouse?

Lockie's Lighthouse is located in the northwestern corner of the map, and is fairly easy to spot. It is located to the northwest of Stealthy Stronghold and Pleasant Park. Once players have located and reached Lockie's Lighthouse, finding and collecting the bottles of Ruby red should not pose a significant challenge.
