This 2018 Volkswagen Jetta bulb size guide is designed to help you verify the correct bulbs by lighting position, so you can replace the right lamp without guessing. Because the Jetta could be equipped with different headlight and taillight packages, the bulb type may change depending on trim, market, and body style.

Use this page as a quick reference for exterior and interior lighting on the 2018 Volkswagen Jetta. You’ll find common fitments for headlights, turn signals, brake lights, reverse lights, license plate lights, dome and map lights, and other interior lamps, which makes it easier to match the bulb to the exact location on the car.

Fitment can vary a lot on the 2018 Jetta, especially between halogen and LED lighting setups. For example, halogen headlight cars use different bulbs than Jetta models with LED headlights or LED tail lights, and some rear lamp positions may be LED-only on certain trims. If you are converting to aftermarket LED bulbs, check for polarity, error messages, and beam pattern before buying a full set. The safest approach is to confirm the bulb already installed in your vehicle and compare it with the position listed here, since the same model year may use different bulbs by package or market.

FAQ

What is the main purpose of this 2018 Volkswagen Jetta bulb size page?

It helps you identify the correct bulb by lighting position, such as headlight, brake light, reverse light, license plate light, or interior lamp. That is especially useful on the 2018 Jetta because bulb sizes can change with trim and lighting package.

Does every 2018 Volkswagen Jetta use the same headlight bulb?

No. The headlight bulb depends on the lighting setup. Some 2018 Jetta models use D3S for the high beam and low beam headlight bulb, while halogen-equipped cars use different bulbs for related front lighting positions.

What bulb does the 2018 Jetta use for the front turn signal?

The front turn signal light bulb is listed as 7507. Always confirm the installed bulb and the exact front lamp housing before ordering, since fitment can vary by market or equipment package.

What is the reverse light bulb for a 2018 Volkswagen Jetta without LED tail lights?

For Jetta models without LED tail lights, the back up reverse light bulb is 921. Models with LED tail lights use a different rear lighting arrangement.

What bulb is used for the rear brake light on a Jetta without LED tail lights?

The brake light bulb for Jetta models without LED tail lights is 7528. On vehicles with LED tail lights, the brake light is part of the LED assembly instead of a replaceable standard bulb.

Which bulb fits the rear turn signal on a 2018 Jetta without LED tail lights?

The rear turn signal light bulb without LED tail lights is 7506. If your Jetta has LED tail lights, the rear signal function may be integrated into the LED unit.

What are the common interior bulb sizes on the 2018 Volkswagen Jetta?

Common interior fitments include 6411 or 6428 for the dome light and trunk or cargo area light, 6428 for the rear reading light, 6418 for the vanity mirror light, 2821 for the glove box and stepwell lights, and 2886X for the door mirror illumination light.

What bulb does the 2018 Jetta use for the license plate light?

The license plate light bulb is listed as LED. If your vehicle has an LED license plate lamp, the bulb may be part of the assembly rather than a standard replaceable incandescent bulb.

Are the parking light and side marker bulbs the same on halogen and LED headlight Jettas?

Not always. Jetta models with halogen headlights use 2825 or 98 for the parking light and front side marker light, while models with LED headlights use LED lighting for those positions.

What should I check before buying bulbs for my 2018 Volkswagen Jetta?

Check the exact lamp position, whether your car has halogen or LED headlights, and whether it has LED tail lights. Then compare the installed bulb number with the listing for that position to avoid ordering the wrong part.

Can I replace LED bulbs on the 2018 Jetta with aftermarket LED conversions?

Yes, in some positions you can, but fitment and performance depend on the housing and electrical system. Aftermarket LED conversions may cause warning lights, flicker, or poor beam pattern, so it is important to test compatibility before replacing multiple bulbs.

Why do some bulb positions on the 2018 Volkswagen Jetta show LED instead of a bulb number?

Those positions are typically built into an LED module or assembly. In that case, the light source is not a standard removable bulb, so the repair may involve replacing the whole unit rather than just the bulb.
