The Night Light provides light, similar to a Campfire, and can only be fueled using Nightmare Fuel (or a Fire Staff in Reign of Giants). One Nightmare Fuel provides light for 175 seconds, and reaches maximum output with 3 Nightmare Fuel. It does not provide warmth, so it will not prevent Freezing. Once placed, the Night Light cannot be moved (only destroyed/deconstructed).
Standing next to an active Night Light lowers the player's Sanity by 3 per minute (except for Willow, who gains up to +7/min). Being near the Night Light at dusk or night increases the total Sanity drain to 8 points per minute. The Sanity drain can be avoided by standing some distance away.
Night Lights can be a useful light source in Caves and Ruins, where there is an abundance of Nightmare Fuel, but has no use on the surface where nightmare fuel is not as plentiful and materials to fuel other fires are.
In all DLCs as well as Don't Starve Together, when a Night Light begins to smolder, it will not burst into flames, but instead, lights up as if it were fueled. Also, Night Lights can be extinguished by an Ice Flingomatic, Luxury Fan, or Ice. Also it does not provide warmth to cause Overheating during Summer or Dry Season.
The Fire Staff can also be used as a way to fuel Night Lights, one fire staff's shot fuels it for 175 seconds, as it is for 1 Nightmare Fuel.
