This 2014 Volkswagen Jetta bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right replacement to the exact lamp on your car. Because trim level, body style, and lighting package can change the fitment, the page separates sedan and wagon applications and also notes halogen, HID, and LED-equipped versions where needed.
Use this page to check common exterior and interior bulbs before you buy. Whether you are replacing a headlight, turn signal, brake light, dome light, license plate light, or small cabin bulb, the 2014 Volkswagen Jetta uses different bulb types depending on where the lamp is located and how the vehicle is equipped.
Fitment on the 2014 Jetta can vary by market and by package, so always confirm the exact lamp position and the lighting setup on your car before ordering. A halogen-equipped sedan may use different headlight and daytime running light bulbs than an HID sedan, and wagon models can differ again from sedans. If you are converting to aftermarket LED bulbs, make sure the new bulb matches the base type, physical size, and any polarity or CAN-bus requirements for your application. The safest approach is to inspect the installed bulb first and compare it with the bulb chart before purchase, especially for exterior lights where the same model year can have several valid options.
Start by matching your body style and lighting package, then find the exact light position, such as low beam, turn signal, brake light, or dome light. The page is organized to help you verify bulb sizes by location instead of guessing from the model year alone.
No. Headlight fitment depends on whether the sedan has halogen or HID headlights. The chart lists H7 for sedan halogen high beam applications, D3S for sedan HID high and low beam applications, and H7 for the low beam listing shown on the page.
The listed high beam bulb for the sedan with halogen headlights is H7. Always confirm the actual headlight assembly on the vehicle before buying, since lighting packages can vary.
For the sedan with halogen headlights, the daytime running light bulb is listed as 7506. Sedan models with HID headlights use a different DRL setup, so the bulb type is not the same across all trims.
The front turn signal bulb is listed as 7507. This is one of the most common exterior bulbs on the car, but you should still check the installed bulb and socket style before ordering.
For a sedan without LED tail lights, the rear turn signal bulb is 7506 and the brake light bulb is 7528. The tail light bulb and rear side marker bulb are also listed as 7528 on those non-LED tail light setups.
On a sedan with LED tail lights, several rear lighting functions are different. The chart lists LED for the brake light, license plate light, tail light, and rear side marker light, while the rear turn signal bulb is 7440A and the back up light bulb is 921.
The wagon rear turn signal bulb is listed as 7507. Wagon lighting can differ from sedan lighting, so do not assume the same rear bulb types across body styles.
For the wagon with HID headlights, the headlight bulb is D1S. For the wagon with halogen headlights, the high beam bulb and daytime running light bulb are both listed as H15.
The chart includes several interior bulb types such as 2825, 98 for map lights and some wagon or front side marker applications, 2821 for glove box, stepwell, courtesy, and wagon front side marker lights, 6411 or 6428 for sedan dome and cargo area applications, 6418 for vanity mirror and wagon dome lights, and 2886X for door mirror illumination.
Yes, many owners choose LED replacements for brighter output or longer life, but the LED bulb must still fit the correct socket and work with the vehicle’s electrical system. Some positions may need resistors or CAN-bus compatible bulbs to avoid warnings or hyperflash.
Yes. That is the best way to avoid mistakes, especially on a 2014 Jetta where trim level, body style, and lighting package can change the bulb type. Comparing the installed bulb to the chart is the most reliable fitment check.
