Rear light malfunctions in the Tesla Model S can pose safety risks and lead to legal issues. Addressing these problems promptly ensures your vehicle remains safe and compliant with traffic regulations.
Common Causes of Rear Light Malfunctions
- Burned-out bulbs

- Water ingress or corrosion
Steps to Diagnose the Issue
Begin by inspecting the rear lights for physical damage or burned-out bulbs. Use the vehicle’s dashboard indicators to identify any warning lights related to lighting issues. Check the fuse box for blown fuses related to the rear lights.
Inspecting the Bulbs and Wiring
Remove the rear light assembly carefully. Examine the bulbs for signs of burning or damage. Inspect wiring connections for corrosion, loose connectors, or broken wires. Replace any damaged components as needed.
Checking Fuses and Modules
Locate the fuse box, typically under the hood or in the trunk. Use the owner’s manual to identify the fuse related to the rear lights. Replace blown fuses with ones of the same amperage. If fuses are intact, consider testing or resetting the light control modules.
Resolving the Issue
If basic troubleshooting does not resolve the problem, it may be necessary to consult a professional technician. They can perform advanced diagnostics, including checking the vehicle’s electronic control units (ECUs) and wiring harnesses.
