Find Light Bulbs in ARC Raiders by looting the Field Depot drawer and white cars on Dam Battlegrounds.
Start with the fixed desk-drawer spawn east of Power Generation Complex, then check the car near Generator Hall's extraction lift. If you're closer to Electrical Substation, its two white cars are another strong target. Light Bulbs also appear in electrical containers, lockers, and vehicles elsewhere, but searching specific containers beats wandering through every building with a lightning bolt icon.
Where should you look for Light Bulbs first?
Dam Battlegrounds is the best map for dedicated Light Bulb farming because it combines fixed spawns with searchable vehicles and electrical loot areas. Your first destination should be a particular drawer or car, rather than an entire industrial complex.
| Location | Exact search target | Reliability | Best for |
|---|---|---|---|
| Field Depot, Dam Battlegrounds | Computer-desk drawer east of Power Generation Complex | Guaranteed spawn if unlooted | A focused first stop |
| Electrical Substation, Dam Battlegrounds | Two white cars on the southern side | Guaranteed spawns if unlooted | Runs centered on the substation |
| Generator Hall, Dam Battlegrounds | Car southeast of the extraction lift, beside abandoned buses | High chance, not a fixed yield | One last search before extraction |
| Pilgrim's Peak, The Blue Gate | Two red lockers in the room below the summit | A reliable Light Bulb target | An alternative to Dam Battlegrounds |
The Field Depot drawer is the simplest container to build a repeatable route around. Generator Hall makes a useful second stop because its car sits close to an extraction point, while the Electrical Substation cars work as a separate starting option.
Dam Battlegrounds loot targets
How do you run the northern Dam Battlegrounds route?
Pair Field Depot with Generator Hall when you want a short farming run. This route gives you a fixed drawer spawn followed by a high-chance vehicle search near extraction, without requiring a sweep of every electrical building.
Find the Field Depot desk drawer
Look for the Field Depot between Power Generation Complex and East Broken Bridge, east of the complex. Inside, find the computer desk in the corner and search its drawer.
- Enter the Field Depot building.
- Locate the computer desk.
- Search the desk drawer for a Light Bulb.
- Continue toward Generator Hall if you still need more.
The drawer contains a guaranteed Light Bulb when another Raider has not emptied it first. That makes it a better first target than opening random containers around Power Generation Complex.
Search the Field Depot drawer
Check the Generator Hall car before leaving
Near Generator Hall, look southeast of the extraction lift for a car beside abandoned buses. Open its hood and search it. This vehicle can contain one or two Light Bulbs, but treat those as a possible haul rather than a promised result.
Combining the Field Depot drawer with this car can produce two to three Light Bulbs in a run. Once you have what you came for, prioritize extraction instead of extending the raid for more containers.
Check the car beside the buses
Where are the Electrical Substation Light Bulb spawns?
At Electrical Substation on Dam Battlegrounds, search the two white cars on the southern side of the location. Check their searchable hoods or trunks for the fixed Light Bulb spawns.
One useful landmark is the space between the broken wire fence and the substation building. The white car there is a specific target, not a reason to search every nearby wreck before checking the objective container.
If the cars have already been looted, the smaller buildings on the northern side of Electrical Substation offer lockers and containers worth checking. These are backup searches, so move on once you have covered them rather than waiting around an emptied vehicle.
For a broader electrical-loot search, Power Generation Complex has underground tunnels below the main building and a control room on its eastern side. Search the containers, cabinets, and computers there when the fixed targets have not supplied enough Light Bulbs.
What are the best backup Light Bulb locations?
Pilgrim's Peak on The Blue Gate is the strongest alternative to the Dam Battlegrounds route. Buried City also works if you're already searching vehicles, while Riven Tides and Pendola Pass offer electrical-loot areas to check during other runs.
Search the red lockers at Pilgrim's Peak
Head to Pilgrim's Peak in the northeast of The Blue Gate. Use your grappling hook to climb the structure, then enter the room immediately below the summit. Search both red lockers inside.
The tower and its outlying buildings also contain electrical loot. You can check the basement control room, although that area commonly produces other electrical items rather than the Light Bulbs you're chasing.
Search below Pilgrim's Peak summit
Pilgrim's Peak is best for players who want a different farming destination after contested Dam Battlegrounds runs. It is still a high-threat area, so plan around the lockers without assuming the tower will be quiet.
Check vehicles and electrical areas on other maps
| Map | Where to search | What to prioritize |
|---|---|---|
| Buried City | Highway, Parking Garage, and car parks near Hospital | Searchable car hoods and bus rear compartments |
| The Blue Gate | Checkpoint | Searchable vehicles |
| Dam Battlegrounds | Ruined road through the middle of the map | Vehicles you pass between objectives |
| Riven Tides | Customs House | Electrical loot in the medium-threat area |
| Pendola Pass | Railroad Junction | Electrical loot alongside mechanical loot |
In Buried City, vehicles are the practical backup because electrical finds are more spread out. Look for intact car hoods and buses with searchable rear sections instead of treating every ruined vehicle as a loot container.
If Cooling Fans are also on your shopping list, use the separate Cooling Fan farming routes to plan that search. The Light Bulb route here stays focused on cars, lockers, and the Field Depot drawer.
Should you keep Light Bulbs or sell them?
Keep Light Bulbs until you've checked your project and event objectives, then sell surplus. They are an Uncommon Trinket, weigh 0.2 each, and stack to 3, so a reserve does not demand much space.
| Use | Light Bulbs required | Context |
|---|---|---|
| Expedition 1, Framework stage | 5 | Historical requirement |
| Expedition 2, Framework stage | 4 | Historical requirement |
| Flickering Flames, second page | 3 | Holiday event objective |
Expeditions 3 through 5 did not require Light Bulbs. The Framework requirements above belong to the earlier Expeditions, which matters if you're following an older checklist.
For Flickering Flames, a reserve of 3 Light Bulbs covers its second-page requirement. The Candleberry farming locations guide covers another resource associated with that event if you're organizing an event checklist.
Common mistakes
The biggest time-waster on Dam Battlegrounds is searching an entire electrical area before checking its known target containers. Fix the search order first, then worry about adding more stops.
- Ignoring vehicles: Light Bulbs can appear under car hoods and in searchable bus rear compartments, including outside electrical zones.
- Treating every electrical container as guaranteed: The fixed Field Depot drawer is a stronger target than a random cabinet at Power Generation Complex.
- Assuming Pilgrim's Peak is safe: Its red lockers are useful, but the location is classified as high threat.
- Continuing after collecting enough: Once your required Light Bulbs are secured, unnecessary fights only put the haul at risk.
- Using an old Expedition count: Expedition 1 needed 5 Light Bulbs, Expedition 2 needed 4, and the feature is currently paused.
Pro tips
Protect Light Bulbs before adding more loot
Choose a custom loadout with an Augment so you have Safe Pocket access, then move the Light Bulbs there. Items in the Safe Pocket survive your death, which is a better result than losing your last required bulb near extraction.
Keep the route short and the searches deliberate
Repeat the Field Depot and Generator Hall route rather than turning every attempt into a full-map clear. The fixed spawns refresh between raids, and short runs let you return to those containers instead of relying entirely on scattered electrical loot.
- Search cars you pass: The ruined central road on Dam Battlegrounds provides extra opportunities without making every vehicle a destination.
- Read the map category: A lightning bolt marks electrical loot areas, useful when your named targets are empty.
- Know your stack size: A stack of 3 Light Bulbs weighs 0.6. It is 3 bulbs per slot, not nine.
- Check conditions before choosing Night Raid: Increased loot value comes with fewer active Return Points and no active Raider Hatches.
Light Bulb FAQ
Can you buy or craft Light Bulbs?
No. Light Bulbs cannot be bought in Speranza or crafted. You need to collect them through Topside looting, which makes the Field Depot drawer and specific white cars useful repeat targets.
Are Light Bulbs only found in electrical zones?
No. Cars, red lockers, and industrial containers can contain Light Bulbs outside dedicated electrical areas. The electrical map category helps narrow your search, but it is not a restriction on every possible spawn.
How many Light Bulbs should you save?
Keeping one stack of 3 is a practical event reserve because Flickering Flames required that amount. Earlier Expedition requirements were different, and Expeditions are paused under patch 1.48.0, so check the relevant objective before committing your stash.
