This 2014 Jeep Wrangler bulb size guide helps you verify the correct bulbs by lighting position, so you can replace a failed lamp with the right fit the first time. Because Wrangler trims, body styles, and lighting packages can vary by market, it is smart to match the bulb to the exact location on your vehicle before ordering.
Use this page as a quick reference for exterior and interior lighting on the 2014 Wrangler, including headlights, turn signals, tail lights, license plate lights, and cabin bulbs. The chart is organized by position, which makes it easier to compare what is installed on your Jeep and avoid confusion between similar-looking bulbs.
For the best fitment results, always confirm your trim level and whether your Wrangler uses factory halogen or an LED setup, since some lighting positions can differ with package changes or aftermarket upgrades. If your Jeep has been converted to LED bulbs, check for load resistors, hyperflash issues, or dimming concerns before buying replacements. When possible, remove the existing bulb and compare the base and markings directly, because the installed bulb is the most reliable way to confirm fitment. This is especially helpful on the 2014 Wrangler, where exterior and interior bulbs may vary by body style, market, or previous owner modifications.
