Tesla Model 3 2019 Bulb Size
Bulb size chart
This page helps you find the right bulb fitment for the 2019 Tesla Model 3 by lighting position, so you can match the correct replacement to the exact lamp you need. Whether you are checking exterior lights or interior courtesy lamps, the goal is to make bulb selection faster and reduce guesswork before you buy.
For the 2019 Tesla Model 3, many lighting functions use LED units rather than traditional replaceable halogen bulbs. That means some positions may be serviced as complete LED assemblies or specific LED modules, depending on trim and market. Use the bulb chart on this page to verify the light location first, then compare it with the part installed on your car.
Fitment can vary by trim, body style, and regional equipment, so it is smart to confirm the exact lamp setup before ordering anything. Some Model 3 lighting positions may be factory LED only, while others can differ if the car has a different package or market-specific configuration. If you are considering an aftermarket conversion, make sure the replacement is compatible with the vehicle’s electrical system and housing design. The safest approach is to check the installed bulb or module before purchase, especially for exterior lights where LED and non-LED setups are not always interchangeable.
FAQ
Does the 2019 Tesla Model 3 use LED bulbs for most lights?
Yes. The bulb chart for this year shows LED lighting in many positions, including headlight high and low beam, fog light front, brake light, turn signals, license plate light, parking light, tail light, daytime running light, reverse light, and several interior lamps.
How do I use this page to find the correct bulb?
Start with the lighting position, such as license plate light, dome light, or rear turn signal. Then compare that position with the chart on this page to confirm the bulb type listed for the 2019 Tesla Model 3.
Are the headlight bulbs replaceable on the 2019 Model 3?
The chart lists the headlight high beam and low beam as LED. In many cases, that means the lighting is integrated or module-based rather than a simple plug-in bulb, so replacement may be different from a standard halogen setup.
What should I know before replacing a front fog light bulb?
The front fog light is listed as LED on the 2019 Tesla Model 3. Before buying a replacement, confirm whether your car uses a serviceable LED module or a complete lamp assembly, since that can vary by configuration.
Are the front and rear turn signal bulbs the same?
Both front and rear turn signal lights are listed as LED, but that does not automatically mean they use the same part or housing. Always verify the exact position on the vehicle before ordering.
Can I replace the license plate light bulb myself?
The license plate light is listed as LED, so replacement may involve an LED module or assembly rather than a standard bulb swap. Check the installed part and the lamp housing design before attempting service.
Does the 2019 Tesla Model 3 have LED interior lights too?
Yes. The chart includes LED glove box light, trunk or cargo area light, dome light, and interior door light. These are useful reference points if you are replacing cabin lighting.
What about the side marker lights on this model year?
Both front and rear side marker lights are listed as LED for the 2019 Tesla Model 3. Because lighting packages can vary, it is still best to confirm the exact lamp in your vehicle before purchasing.
Is the back up reverse light the same as the back up light bulb?
The page lists both back up reverse light bulb and back up light bulb as LED references. Depending on the vehicle configuration and how the lamp is labeled in a catalog, they may point to the same rear reverse-light function, so check the installed lighting position carefully.
Do trim and market differences matter for bulb fitment?
Yes. Trim level, body style, and market can change the lighting package on a 2019 Tesla Model 3. A bulb or module that fits one version may not match another, even within the same model year.
Should I check the old bulb before ordering a replacement?
Absolutely. Checking the installed bulb or module is one of the best ways to avoid ordering the wrong part, especially on a Tesla where many lights are LED-based and may not use a standard removable bulb.
Can I convert a non-LED setup to LED on this car?
Some aftermarket conversions may be possible, but compatibility depends on the housing, connector, and vehicle electronics. Make sure the replacement is designed for the 2019 Tesla Model 3 and is suitable for the specific lighting position.
