This 2020 Jeep Grand Cherokee bulb guide helps you verify the correct bulb size by lighting position, so you can replace the right lamp the first time. Whether you are changing a headlight, tail light, turn signal, or interior bulb, matching the bulb to the exact location is the safest way to avoid fitment mistakes.
Bulb sizes on the Grand Cherokee can vary by trim, lighting package, market, and body style. This page organizes the common exterior and interior bulb positions for the 2020 Jeep Grand Cherokee so you can compare the installed bulb with the chart before buying a replacement.
For best results, confirm your trim and headlight setup before ordering, since some 2020 Grand Cherokee models use different bulbs for halogen and LED-equipped lighting systems. Aftermarket LED conversions may fit physically but still require the correct base, polarity, and sometimes extra hardware or resistors to work properly without warnings or flicker. If you are unsure, remove the old bulb and check the number printed on the base before purchase, especially for common positions like H11, H9, D3S, 3157, 7440, 7440A, 7444NA, 921, 906, 194, 168, 214-2, and 74.
The chart lists H11 for the low beam headlight on some 2020 Jeep Grand Cherokee setups. Other lighting configurations may use D3S for combined high beam and low beam systems, so check your specific trim before ordering.
The high beam headlight is listed as H9 on certain 2020 Grand Cherokee models. Some versions with different headlamp assemblies may use D3S, so the installed bulb should be verified against the vehicle.
The front fog light bulb is listed as H11, with H11 LED also shown as an option on some applications. Make sure the replacement matches the original housing and any factory lighting package.
The daytime running light is listed as H11, with H11 LED also shown for some configurations. Because DRL setups can differ by trim and market, it is smart to confirm the bulb already in the vehicle.
The front turn signal bulb is listed as 7444NA. This is a specific amber-style application, so it should be matched closely to maintain proper signaling and appearance.
The rear turn signal bulb is listed as 7440A or 3157, depending on the configuration. If you are replacing only one side, compare the old bulb number before buying a pair.
The brake light bulb is listed as 3157R or 3157. The exact bulb can depend on the lamp assembly, so checking the installed bulb is recommended before replacement.
The tail light bulb is listed as 3157. If your Grand Cherokee has LED tail lamps, the bulb may not be serviceable in the same way as a standard replaceable bulb setup.
The chart lists 921 for the inner back up light and 7440 for the outer back up light. Some vehicles may use only one of these positions depending on the rear lamp design.
The license plate light bulb is listed as LED on this page. Since the exact service part can vary with the lamp assembly, confirm the original bulb or housing type before purchasing.
Interior and cabin-related bulbs listed include courtesy light 168, glove box light 194, stepwell light 906, trunk or cargo area light 214-2, and several indicator bulbs such as 74 for the instrument panel, turn signal indicator, high beam indicator, parking brake indicator, and check engine light.
No. Trim level, lighting package, market, and body style can change the bulb type used in several positions. That is why it is important to verify the exact bulb by location instead of relying only on the model year.
Yes, in some positions you can use LED replacements, but fitment is not always plug-and-play. You should confirm bulb base, size, beam pattern, and whether the vehicle needs extra components to avoid warnings, flicker, or poor light output.
The most reliable method is to check the bulb chart by lighting position and compare it with the bulb removed from the vehicle. Reading the number on the bulb base is especially helpful when the trim or lighting package is unclear.
