The Flashlight provides light in dark underwater areas. It uses battery power and can be equipped from your toolbar for quick access while exploring.

Flashlight Crafting

Unlock Flashlight Blueprint

To unlock the Flashlight blueprint in Subnautica 2, you need to scan 2 Flashlight Fragments using the Scanner tool.

Flashlight Crafting Recipe

The Flashlight can be crafted in the Fabricator using Titanium and Quartz and Basic Battery required to power the Flashlight during exploration.

Use Fabricator to Craft Flashlight

The Flashlight can be crafted in the Fabricator after unlocking its blueprint. Collect the required materials in advance so you can craft it once the blueprint is unlocked.

Can the Flashlight Be Upgraded?

Currently, the Flashlight does not have upgrade modules. However, players can improve exploration efficiency by carrying extra batteries or using vehicles equipped with external lighting systems.

Flashlight Fragments Location

Flashlight Fragment Location 1

From Camp One, which is located 270m North-northeast of the Lifepod, head towards the nearby wreck located roughly 200m away. Enter the wreck through the broken opening. The Flashlight Fragment can be found near the back section of the wreck beside scattered equipment and debris.

Flashlight Fragment Location 2

Sophie’s Retreat is located inside a cave near the Old Habitat. Follow the left cave wall until you spot two Medical Gel Sacs, then locate the hatch entrance and explore the bunker interior to find a scannable Flashlight Fragment near the furniture and storage areas.

Flashlight Use

Flashlight Uses

The Flashlight is one of the most useful early-game tools, allowing you to explore dark caves, wrecks, and deep underwater areas with better visibility.

Unlock Databank Entry

Unlocking and crafting the Flashlight also adds its databank entry to your PDA. The entry contains basic information about the tool and its function during exploration.

Flashlight Tips

Flashlight Uses Battery Power

The Flashlight consumes battery power while active. Carry spare Basic Batteries during long exploration trips so you do not lose visibility inside caves or wrecks.

Conserve Battery Life

Turn off the Flashlight when traveling through bright areas to conserve battery power. This helps prevent the Flashlight from running out of energy during deep exploration, wreck searches, or cave dives where visibility becomes more important.
