Where to Find Lightbulbs in ARC Raiders
Lightbulbs are rare electrical components for Framework (3/6). This guide mirrors the December 2025 reference runs: one guaranteed drawer and one breachable car hood in Dam Battlegrounds, plus a quiet Blue Gate locker at Pilgrims Peak. Each loop is built to finish 5 Lightbulbs quickly while stacking Batteries and Sensors.
Expedition stage
Caravan Expedition Stage 3 / 6 - Framework
Primary need
5x Lightbulb (Electrical loot)
Also needed
30x Battery / 20x Sensors / 1x Exodus Module
Best sources
Dam Field Depot & Generator Hall / Blue Gate Pilgrims Peak
Why Lightbulbs matter
Framework (Stage 3/6) needs 5 Lightbulbs to build the Caravan walls and roof systems. They only roll in Electrical loot, so chasing random zones is slow. Use the two guaranteed Dam pulls and the Blue Gate locker to get them without relying on RNG.
Route 1: Dam Battlegrounds - two guaranteed pulls
Both spawns sit near Generator Hall extract, making this the fastest loop. Grab the drawer, then the car hood, extract, and reset.

Steps
- 1) Load into Dam Battlegrounds. Any loadout works; lighter is faster.
- 2) Field Depot drawer (guaranteed). Inside the depot between Power Generation Complex and East Broken Bridge; open the corner computer desk drawer for 1x Lightbulb.
- 3) Generator Hall car hood (guaranteed). Near the Generator Hall extract, breach the hood of the car by the bus for another Lightbulb.
- 4) Extract at Generator Hall. Bank both Lightbulbs and reset.




Route 2: Blue Gate - Pilgrims Peak locker
A quieter backup if Dam is contested. One red locker inside Pilgrims Peak holds a guaranteed Lightbulb.

Steps
- 1) Load into Blue Gate. Bring a basic kit; travel light.
- 2) Climb Pilgrims Peak. Grapple or climb toward the top, then drop into the interior room before the summit.
- 3) Open the two red lockers. One of them is a guaranteed Lightbulb if unlooted.
- 4) Extract at the nearest point. Reset if the locker is empty; contest is usually low.




Fast loop script (3-6 minutes)
- 1) Queue Dam -> Field Depot drawer -> car hood -> Generator Hall extract.
- 2) If Dam is picked clean, queue Blue Gate -> Pilgrims Peak lockers -> extract.
- 3) Alternate until 5x Lightbulbs are secured; grab Batteries and Sensors along the way.
- 4) Pair with other electrical runs (Cooling Fans, Sensors) to finish multiple steps together.
Loadout and pacing tips
- Go light; Lightbulbs are small, so speed and stamina perks beat extra capacity.
- Carry a breach tool for the car hood; a lockpick helps with side lockers but avoid long detours.
- Night/off-peak queues reduce contest at Dam; Blue Gate is naturally quieter.
- Duo split: one player camps Dam guaranteed spawns while another runs Blue Gate to parallelize the 5-Lightbulb requirement.
After you have 5
- Finish Framework by combining Lightbulbs with Batteries, Sensors, and the Exodus Module.
- Recycle spare electrical junk per the loot page to free stash space.
- Use the same Dam loop to double-dip for Cooling Fans or Sensors if you still need them.
