OEM Replacement Trunk Light — Perfect factory fit and straightforward swap
Why we like it: This is the exact part Tesla uses, so compatibility is guaranteed, and it restores the original look and function. Installation is a simple plug-and-play process that most owners can handle in minutes with basic tools. It’s the no-fuss solution for those who want to fix the problem without any modifications.
Who it’s for: Owners who prefer a stock restoration and don’t need extra brightness or features.
Installation: Easy | Compatibility: Model 3 (also compatible with Model Y trunk lights)
Aftermarket LED Trunk Light Bar — Significantly brighter illumination
Why we like it: These LED bars often produce a much whiter, more powerful light than the stock unit, making it easy to see every corner of your trunk. Many come with adhesive backing or simple mounting brackets, and they can often tap into the existing wiring. They’re a popular upgrade discussed in communities like r/TeslaModel3 for their improved visibility.
Who it’s for: Owners who want better-than-stock lighting and don’t mind a minor DIY project.
Installation: Medium (may require wiring) | Compatibility: Model 3 and Model Y
Magnetic Motion-Sensor Trunk Light — Easy, no-wire installation
Why we like it: These battery-operated lights attach magnetically or with adhesive and turn on automatically when motion is detected, offering a true plug-and-play solution. They’re ideal for quick fixes without touching the car’s electrical system. While they aren’t integrated like built-in lights, they provide reliable, temporary illumination.
Who it’s for: Renters, those wary of car modifications, or anyone needing a fast, temporary fix.
Installation: Easy | Compatibility: Both Model 3 and Model Y
USB Rechargeable Portable Trunk Light — Flexible and portable
Why we like it: Similar to the magnetic option, these lights are completely independent of the car’s power. You can recharge them via USB and place them anywhere in the trunk. They offer great flexibility, as you can also use them in other areas of the car or even take them out for camping.
Who it’s for: Owners who want a versatile light source not permanently fixed to the vehicle.
Installation: Easy | Compatibility: Universal (works in any Tesla)
DIY LED Strip Installation — Custom lighting configurations
Why we like it: For the hands-on enthusiast, using generic LED strips allows for complete customization of color, brightness, and placement. You can wire them into the trunk’s 12V circuit for a seamless look. This approach is popular on forums where owners share their creative setups, though it requires more technical skill.
Who it’s for: DIYers and tinkerers who enjoy personalizing their car’s interior lighting.
Installation: Medium to Hard (requires wiring and soldering knowledge) | Compatibility: Model 3 (and Model Y with adaptation)
Trunk Light Fuse & Wiring Check — Diagnosing underlying electrical issues
Why we like it: Before buying any replacement, it’s smart to diagnose the root cause. The trunk light fuse is often located in the interior fuse box, and checking it costs nothing. This step, recommended on r/TeslaMotors, can save you from purchasing an unnecessary new light if the issue is just a blown fuse or loose connector.
Who it’s for: All owners experiencing the problem—this should be your first troubleshooting step.
Installation: Easy (diagnostic) | Compatibility: Model 3 and Model Y

What to Look for in a Tesla Trunk Light
When choosing a fix or upgrade for your Tesla Model 3 trunk light not working, consider several key factors. First, brightness and color temperature are crucial; you want a light that’s bright enough to see clearly but not so harsh that it causes glare. LEDs in the 5000K-6000K range offer a clean, white light ideal for utility. Second, power source and installation method matter—do you want a solution that uses the car’s existing wiring for a permanent feel, or a battery-powered option for simplicity? Third, build quality and durability ensure the light withstands trunk vibrations and temperature changes. Finally, compatibility is non-negotiable; always verify the product is designed for the Tesla Model 3 (or Model Y if you own that model) to avoid fitment issues. For a deeper dive into Tesla’s vehicle specifications, you can check the official Model 3 page.

Frequently Asked Questions
Is the trunk light issue covered under Tesla’s warranty?
It depends on your vehicle’s age and warranty status. If the light failed due to a manufacturing defect and your car is within the Tesla New Vehicle Limited Warranty period, it should be covered. However, wear and tear or modifications typically aren’t. It’s best to contact Tesla Service to diagnose the specific cause.
Can a non-working trunk light drain my Tesla’s battery?
A standard trunk light draws minimal power when off, so a faulty switch that leaves it on constantly could cause a very slow drain over several weeks. However, this is rare. If you suspect a parasitic drain, it’s more likely related to other electronics; a service center can run a diagnostic.
Why did my Model 3 trunk light stop working suddenly?
Common reasons include a burnt-out LED (though LEDs have long lifespans), a blown fuse, or a loose wiring harness connector—especially after heavy trunk use. As discussed in owner forums, sometimes the issue is a software glitch, which a software update or a car reboot might fix. Start by checking the fuse before replacing the light unit.
