The Light Bulb is an uncommon trinket item. It is a necessary component for completing various projects, such as Expedition 1 and Expedition 2.
You can find these by scavenging in the Electrical Substation area of the Dam Battlegrounds map, frequently appearing inside cars and car hoods. They are also present in car hoods near the Extraction Lift in the Generator Hall area of the Dam Battlegrounds map. Additionally, look for them within loot containers and industrial loot containers at Pilgrim's Peak in The Blue Gate map.
The Light bulb in ARC Raiders is a rare electrical component needed for Part 3 of 6 – Framework in the Expedition Project. You’ll need 5 Light bulbs to help build the Caravan’s walls, roof, and core systems. While Light bulbs can drop in general Electrical Loot Zones, the best way to farm them is by using a couple of guaranteed spawn locations in Dam Battlegrounds and Blue Gate.
Why You Need Light bulbs
For Framework (3/6) in the Expedition Project, you’ll need:
Because Light bulbs are classified as electrical items and are quite rare in standard loot pools, relying only on random Electrical Zones (like Power Generation Complex) can be slow. Using guaranteed spawns makes this part of the Expedition far more efficient.
Dam Battlegrounds Light bulb Location
Step 1: Load into Dam Battlegrounds
Equip either your preferred loadout or a free loadout and load into the Dam Battlegrounds map. Light bulbs here are tied to a couple of fixed spots, so you don’t need to rely on RNG as much.
You can use the Dam Battlegrounds Interactive Map to help you navigate: Dam Battlegrounds Map
Step 2: Loot the Field Depot Drawer
From the north side of the map, move between Power Generation Complex and East Broken Bridge. In this area, you’ll find a Field Depot building.
Head inside and look for a computer desk with a lootable drawer in the corner. Opening this drawer gives you a guaranteed Light bulb (assuming no one else has looted it first).
Step 3: Breach the Car Hood at Generator Hall
Next, travel toward the Generator Hall extraction point. Close to the extraction zone, beside a bus, you’ll see a car with a breachable hood.
Breach the hood, and you’ll usually find 1–2 guaranteed Light bulbs inside. Combined with the Field Depot drawer, this run alone can yield 2–3 Light bulbs in a single visit.
Step 4: Extract Safely
Once you’ve looted both the Field Depot drawer and the car hood, use the Generator Hall extraction point right next to you.
This makes the Dam Battlegrounds route one of the fastest ways to stock up on Light bulbs in just a few quick runs.
Blue Gate Light bulb Location
If Dam Battlegrounds is highly contested or already looted, Blue Gate offers a strong backup method with more consistent safety.
Step 1: Load into Blue Gate
Equip a basic loadout (or free loadout) and enter the Blue Gate map. This area has fewer players contesting the specific Light bulb spawn, making it ideal for repeated solo runs.
Use the Blue Gate Interactive Map for navigation: Blue Gate Map
Step 2: Head to Pilgrim’s Peak
Once in Blue Gate, move to the north-east side of the map and make your way to Pilgrim’s Peak.
Step 3: Climb, Drop In, and Loot the Red Locker
Use the grapple to climb toward the top of Pilgrim’s Peak.
Just before you reach the summit, jump off into the room below rather than going all the way to the top.
Inside this room, you’ll find two red lockers. One of these lockers contains a guaranteed Light bulb. This spot is especially good because it’s less obvious and sees less competition than Dam Battlegrounds’ guaranteed spawns.
Step 4: Extract and Repeat
Once you’ve looted the locker, head to the nearest extraction point and extract safely.
