This 2021 Tesla Model S bulb size page is designed to help you verify the correct bulb or light type by lighting position, so you can match the right part before ordering. Because Tesla uses different lighting setups across trims, markets, and body styles, checking the exact location matters just as much as checking the model year.
For the 2021 Tesla Model S, many exterior and interior positions use LED lighting, including the fog light, brake light, turn signal, license plate light, parking light, tail light, daytime running light, back up light, and several cabin lights. The headlight listing may vary by configuration, with 9005 and D3S shown in the raw fitment data for high beam and low beam use.
Fitment can vary by trim, lighting package, and region, so it is smart to confirm the installed bulb or lamp assembly before buying replacements. Some positions on this Model S are LED modules rather than traditional replaceable halogen bulbs, and aftermarket conversions may not match the original beam pattern, connector style, or error-free operation. If your car has been modified, or if you are unsure whether the vehicle uses a serviceable bulb or a sealed LED unit, inspect the part already installed and compare it with the vehicle’s build details before purchase.
FAQ
What bulbs does the 2021 Tesla Model S use for the headlights?
The available fitment data lists 9005 and D3S for the headlight high beam and low beam setup. Because Tesla lighting can vary by trim and market, confirm which headlight type is installed on your specific vehicle before ordering.
Are the fog lights on the 2021 Model S replaceable bulbs?
The page lists the front fog light as LED. In many cases that means the lighting is part of an LED assembly rather than a simple plug-in bulb, so verify the exact lamp design on your car before purchasing parts.
Does the 2021 Tesla Model S use LED brake lights?
Yes. The brake light is listed as LED for this model year, which usually indicates an integrated LED light source rather than a standard replaceable incandescent bulb.
What should I check before replacing a rear turn signal bulb?
The rear turn signal is listed as LED, so first confirm whether your vehicle has a replaceable bulb or a sealed LED module. Also check the connector shape and housing style, since those can differ by market and body style.
Is the license plate light on the 2021 Model S LED?
Yes, the license plate light is listed as LED. If the light is out, the issue may be the module, wiring, or housing rather than a traditional bulb filament.
Can I swap the interior lights to a different bulb type?
The glove box, dome, map, interior door, and trunk or cargo area lights are listed as LED. If you want to change color or brightness, make sure any aftermarket replacement is compatible with the original voltage, size, and polarity.
Do all 2021 Tesla Model S trims use the same bulb sizes?
Not always. Trim level, lighting package, market, and body style can change the exact fitment, especially for headlights and exterior lamp assemblies. Always verify by position and build configuration.
What is the correct bulb for the back up light on this car?
The back up reverse light and back up light positions are both listed as LED on this page. Because Tesla may use different lamp assemblies depending on configuration, check the installed unit before ordering.
Are the daytime running lights and parking lights LED on the 2021 Model S?
Yes. The available data lists both daytime running light and parking light as LED, which is common on this model year.
How do I know if my car has a serviceable bulb or a sealed LED unit?
Look at the existing lamp assembly and compare it with the part location on the vehicle. If the light is integrated into a sealed housing with no removable bulb access, it is likely an LED module rather than a standard bulb.
Can aftermarket LED conversions cause problems on the 2021 Model S?
Yes, they can. Aftermarket conversions may create fitment issues, warning messages, poor beam pattern, or compatibility problems if the original system was designed for a specific bulb type or LED module.
Why does the page show several LED positions instead of exact bulb numbers?
For many lighting locations on the 2021 Tesla Model S, the available fitment information identifies the light source as LED but does not provide a separate service bulb number. In those cases, the safest approach is to match the lamp assembly or verify the installed part directly.
