Tesla Model 3 2020 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2020 Tesla Model 3 by lighting position, so you can match the correct bulb to the right spot before ordering. Whether you are replacing an exterior lamp or an interior light, checking the location first is the easiest way to avoid buying the wrong part.
For the 2020 Tesla Model 3, many lighting points use LED units rather than traditional replaceable bulbs. That means some items may be serviced as complete LED assemblies instead of a simple bulb swap. Use this year page as a quick reference for the bulb chart and the lighting positions listed for this model.
Fitment can vary by trim, market, and body style, so always confirm the exact lighting setup on your car before purchase. Some Model 3 versions may use different LED modules or package-specific parts, and aftermarket conversions can change what fits or how it functions. If your car was modified, or if you are unsure whether a light is factory LED or an added retrofit, check the installed bulb or assembly before ordering replacement parts. This is especially important for exterior lights, where a halogen-style replacement may not apply if the vehicle uses an integrated LED unit.
FAQ
Does the 2020 Tesla Model 3 use LED bulbs for most lights?
Yes, the bulb chart for the 2020 Tesla Model 3 shows LED lighting for most exterior and interior 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 cabin lights.
Can I replace the headlight high beam and low beam bulb separately on this Model 3?
The chart lists the headlight high beam and low beam as LED. On many 2020 Model 3 setups, that means the lighting is part of an LED assembly rather than a standard replaceable bulb. Check the exact headlamp configuration on your car before ordering parts.
What bulb size does the front fog light use on a 2020 Tesla Model 3?
The front fog light is listed as LED. Because Tesla often uses integrated LED lighting, the replacement may be an LED module or complete lamp assembly rather than a conventional bulb size.
Are the brake lights and center high mount stop light replaceable bulbs?
The chart lists both the brake light and the center high mount stop light as LED. In many cases, these are integrated LED units, so you may need to replace the full light assembly instead of a single bulb.
What should I know about the front and rear turn signal lights?
Both the front turn signal light and rear turn signal light are listed as LED on the 2020 Tesla Model 3. Fitment can vary by market, so verify whether your vehicle uses a serviceable LED module or a sealed assembly.
Is the license plate light on the 2020 Model 3 an LED bulb?
Yes. The license plate light is listed as LED, which is common on this model. If one side is out, inspect the housing and connector as well as the light source before replacing parts.
Do the parking lights and daytime running lights use the same type?
The chart lists both parking light and daytime running light as LED. Even when both are LED, they may be separate functions or integrated into the same lamp assembly depending on the trim or lighting package.
What about the back up reverse light and back up light entries?
The page lists back up reverse light as LED, and also includes a back up light bulb entry marked LED. Because naming can differ by market or body style, compare the chart entry with the actual lamp position on your vehicle before buying.
Are the interior lights on the 2020 Tesla Model 3 also LED?
Yes. The glove box light, trunk or cargo area light, dome light, and interior door light are all listed as LED. These are usually easier to identify once you open the panel or lens and inspect the installed light source.
Do trim level or market differences affect bulb fitment on this year?
Yes. Trim and lighting package can vary by market and body style, so the exact bulb or LED module may differ even within the same model year. Always match the part to your specific vehicle configuration.
Should I check the installed bulb before ordering a replacement?
Absolutely. Checking the installed bulb or assembly is the best way to confirm fitment, especially on a 2020 Tesla Model 3 where many lights are LED and may not use a standard replaceable bulb.
Can I convert a factory LED light to an aftermarket bulb setup?
Aftermarket conversions are possible in some cases, but they may not be plug-and-play and can affect fit, function, or warning messages. For the cleanest result, confirm the factory lighting type first and choose parts designed for your exact Model 3 configuration.
