2024-2026 Tesla Cybertruck Cargo Light: Side-Specific Part Numbers & Replacement Guide
This guide covers failure diagnosis, side-specific part numbers, and a step-by-step replacement walkthrough for the 2024-2026 Cybertruck's bed lights.
- The left (driver) and right (passenger) side cargo lights use different part numbers (1806766 and 1806767 respectively) and are not interchangeable.
- Replacement is a feasible DIY job but requires removing the upper bed side wall trim panel to access the light's mounting bolts.
- Failures are most commonly due to physical damage or water intrusion; no widespread electronic defects are known at this time.
- When buying a used light, prioritize inspecting the mounting tabs and lens for cracks over cosmetic scuffs.
Identifying the Correct Cybertruck Cargo Light
The most critical step in sourcing this part is identifying the correct side. The driver and passenger side cargo lights are not interchangeable and have unique part numbers. Ordering the wrong side will result in a part that does not fit.
| Side | Common Part Numbers |
|---|---|
| Left (Driver Side) | 1806766-00-C, 1806766-00-E |
| Right (Passenger Side) | 1806767-00-C, 1806767-00-D |
Pro Tip: The last letter in the part number (e.g., -C, -D, -E) indicates a revision. Newer revisions are generally acceptable substitutes for older ones, but always confirm with the seller. The first seven digits are the most important for identifying the base part and its designated side.
Symptoms of Failure
As the Cybertruck is a relatively new vehicle, widespread, chronic failure patterns for the cargo light have not yet emerged. However, failures that do occur will likely stem from common issues affecting modern LED vehicle lighting or physical use.
- Light is Completely Out: This is the most common symptom. The LED module may have failed internally, or there could be a wiring or connector issue. Before replacing the light, check the on-screen controls to ensure the lights are enabled.
- Flickering or Dim Light: An LED that flickers or appears dim often points to a failure in the light's internal circuitry or a poor electrical connection. Reseating the electrical connector may solve the issue, but it often requires replacement of the unit.
- Water Intrusion: If you notice condensation or water inside the lens, the unit's seal has failed. This moisture will quickly lead to corrosion and failure of the electronic components. A water-damaged light must be replaced.
- Physical Damage: Given their location in the cargo bed, these lights are susceptible to damage from shifting cargo. Cracks in the lens or housing can allow water to enter and will eventually lead to failure.
Buying a Used Cargo Area Light
For a new vehicle like the Cybertruck, a used OEM light is often the most practical and cost-effective repair option, as direct-fit aftermarket alternatives are not yet widely available. Here’s what to inspect before buying:
- Verify the Part Number: Double-check that you are buying the correct part number for the side you need to replace (1806766 for Left, 1806767 for Right).
- Inspect the Mounting Tabs: The light assembly is secured by three bolts. Carefully inspect the plastic housing and ensure all mounting points are intact and free of cracks. A broken tab will prevent the light from being installed securely.
- Check the Lens and Housing: Look for any cracks, even hairline fractures, in the clear lens or the black plastic housing. A compromised housing will not be weatherproof and will fail prematurely. Minor surface scuffs are acceptable, but deep scratches or cracks are a major red flag.
- Examine the Electrical Connector: The connector pins should be straight, clean, and free of any green or white corrosion. The plastic connector housing should not be cracked or chipped.
- Ask About the Donor Vehicle: Whenever possible, inquire about the history of the Cybertruck the part came from. Parts from low-mileage, collision-damaged vehicles are ideal. Avoid parts from vehicles with flood or fire damage, as these can cause hidden electrical issues.
Replacement Overview (Difficulty: 3/5)
Replacing the cargo area light is a feasible DIY project for someone with basic mechanical skills, but it does require removing a large trim panel. The official Tesla service procedure outlines the steps clearly. The process is the same for both left and right sides.
Tools Required:
- Trim removal tool
- 10mm socket
- Torx T20 socket
- Ratchet
Step-by-Step Procedure:
- Prepare the Vehicle: Open the tonneau cover and lower the tailgate for access.
- Remove Upper Bed Side Wall: Starting from the rear of the bed, use a trim tool to carefully release the eight clips holding the upper bed side wall assembly (the panel directly above the light). Lift the tonneau cover's rubber seal as needed to get access. Once all clips are free, remove the panel from the vehicle.
- Access Lower Wall Fasteners: With the upper panel removed, locate and remove the four upper 10mm fasteners on the lower bed side wall panel. This provides the necessary flex to access the light.
- Remove the Light Assembly: The light is held in by three bolts. Remove these bolts (a T20 Torx may be needed for some fasteners). Disconnect the electrical connector and carefully maneuver the light assembly out of the vehicle.
- Installation: Installation is the reverse of removal. Position the new light, connect the electrical plug, and install the three mounting bolts. Torque the light assembly bolts to 2.5 Nm (1.8 lb-ft).
- Reassemble Trim: Reinstall the four 10mm fasteners for the lower wall panel, torquing them to 11 Nm (8.1 lb-ft). Align the upper bed side wall panel and press firmly to engage all eight clips.
- Test the Light: Use the vehicle's touchscreen to turn the cargo lights on and confirm the new light is functioning correctly.
Warning: Always use plastic trim removal tools to avoid scratching the composite bed panels. Be gentle when releasing the clips, as they can break if forced.
Cost Comparison
Pricing for Cybertruck parts can vary, but this provides a general estimate.
| Part Source | Estimated Cost |
|---|---|
| New OEM (Dealer) | $120 - $200 (estimate, contact dealer for exact price) |
| New Aftermarket | Not Widely Available |
| Used OEM | $75 - $125 |
| Shop Labor | $50 - $100 |
Known Issues, TSBs, and Recalls
As of mid-2024, there are no specific recalls, Technical Service Bulletins (TSBs), or widespread owner complaints related to the failure of the cargo area lights on the 2024-2026 Tesla Cybertruck. While the vehicle has been subject to several recalls for other issues like the accelerator pedal and wiper motor, the bed lighting has so far proven reliable.
Frequently Asked Questions (FAQ)
Are the left and right Cybertruck cargo lights the same part?
No, they are not interchangeable. The driver's side (left) uses part number 1806766-XX-X and the passenger's side (right) uses 1806767-XX-X. You must order the specific part for the side you are replacing.
Do I need to program a new cargo light after installation?
No. The cargo area light is a simple plug-and-play component. The vehicle does not require any special software calibration or programming after replacement.
My cargo light stopped working. What should I check first?
First, go to Controls > Lights on your touchscreen and ensure the 'Bed Lights' are set to 'On' or 'Auto'. If the setting is correct, the next step is to inspect the light for physical damage or water inside the lens. If there is no visible damage, the unit has likely failed internally and requires replacement.
Can a car wash cause the cargo lights to fail?
While some early Cybertruck owners have reported various electronic issues after using automated car washes, this is not a known specific cause for cargo light failure. However, if a light's seal is already compromised, high-pressure water could force its way in and cause a short circuit.
