This page covers the 2020 Volkswagen Jetta bulb sizes by lighting position, so you can quickly verify the correct replacement for each exterior and interior lamp. Because the Jetta can use different lighting setups depending on trim, market, and body style, checking the bulb chart by location is the safest way to match the right part before you buy.
For the 2020 Volkswagen Jetta, many exterior functions are listed as LED, including the low beam, high beam, brake light, license plate light, tail light, daytime running light, and reverse light. Interior and auxiliary bulbs may use different sizes, such as 2825/98, 6411/6428, or 6418, so this page helps narrow down the correct bulb size for each specific position on the car.
Fitment can vary by trim package, lighting option, and market, so always compare the bulb position on your Jetta with the chart before ordering. Some cars use factory LED assemblies, while others may have halogen-style housings or mixed setups, and aftermarket LED conversions can change the required bulb type or connector style. If you are replacing a bulb, it is a good idea to remove the installed bulb first and confirm the marking on the base, especially for fog lights, front turn signals, and interior lamps where multiple sizes may be listed.
FAQ
What bulb sizes does the 2020 Volkswagen Jetta use for the headlights?
The 2020 Volkswagen Jetta page lists LED for both the headlight low beam and headlight high beam. Because lighting equipment can vary, confirm the exact headlight setup on your vehicle before ordering replacements.
Are the brake lights on the 2020 Jetta LED or halogen?
The bulb chart shows the brake light bulb as LED for the 2020 Volkswagen Jetta. If your car has a factory LED rear lamp assembly, the replacement may be part of the complete housing rather than a simple single bulb swap.
What is the license plate light bulb size for this Jetta year?
The license plate light bulb is listed as LED on the 2020 Volkswagen Jetta. That means the light source is typically integrated into an LED unit, so fitment can depend on the exact rear lamp design.
Which bulb is used for the front fog lights?
The front fog light bulb options listed are H11 LED and H16 LED. The correct choice depends on the trim and lighting package, so check the installed bulb or the factory housing before purchasing.
What bulb does the front turn signal use on the 2020 Volkswagen Jetta?
The front turn signal light bulb is listed as 64132. Since front signal fitment can differ by market and equipment level, verify the bulb in the vehicle before replacing it.
Does the rear turn signal use the same bulb as the front?
No. The rear turn signal light bulb is listed separately and shown as LED, while the front turn signal uses 64132. This is a good example of why checking by lighting position matters.
What bulb size is used for the map light and rear reading light?
Both the map light bulb and the rear reading light bulb are listed as 2825 and 98. These interior bulbs are often interchangeable in many applications, but it is still best to confirm the installed bulb shape and base.
What bulb is used for the dome light and vanity mirror light?
The dome light bulb and vanity mirror light bulb are both listed as 6418 on the 2020 Volkswagen Jetta. If you are upgrading to LED, make sure the replacement matches the original size and fits the housing depth.
What is the trunk or cargo area light bulb size?
The trunk or cargo area light bulb is listed as 6411 or 6428. Either size may appear depending on the exact lamp assembly, so checking the existing bulb is recommended before ordering.
Are the side marker lights LED on this model?
Yes, both the front side marker light bulb and rear side marker light bulb are listed as LED for the 2020 Volkswagen Jetta. In many cases, that means the lamp is part of an LED assembly rather than a standard replaceable bulb.
Can I convert halogen bulbs to LED on a 2020 Volkswagen Jetta?
Yes, some owners choose aftermarket LED conversions, but compatibility depends on the housing, connector, and vehicle electronics. A conversion may require error-free bulbs, adapters, or additional coding, so it is important to verify fitment before buying.
Why should I check the installed bulb before replacing it?
Because trim and lighting package differences can change the bulb type, checking the installed bulb helps prevent ordering the wrong part. This is especially useful for fog lights, interior lamps, and any position where more than one bulb size is listed.
