This 2014 Acura MDX bulb size guide helps you verify the correct bulbs by lighting position, so you can replace a failed lamp without guessing. Whether you are checking the headlights, interior lights, or exterior signal bulbs, this page organizes the common fitments for the 2014 Acura MDX in a simple way that is easy to compare before you buy.
Because the 2014 Acura MDX may use different lighting setups depending on trim, market, and body style, it is important to match the bulb to the exact location on the vehicle. This page covers the most commonly listed bulb positions for the MDX and can help you confirm whether a bulb is used for low beam, high beam, turn signal, reverse light, or cabin lighting.
For best results, compare the bulb position on your vehicle with the chart before ordering, especially if your MDX has a trim or lighting package that differs from another market. Some locations may use LED assemblies, while others use replaceable halogen-style bulbs, and aftermarket LED conversions can change fitment, brightness, or warning behavior. If you are replacing a bulb, it is smart to remove the installed bulb and check the number printed on it before purchase, since the same model year can have more than one valid option in certain positions.
It helps you match the bulb size or bulb type to a specific lighting position on the 2014 Acura MDX, such as the low beam, rear turn signal, license plate light, or interior dome light.
Yes. The chart for this page lists both the headlight low beam and headlight high beam as LED, which means the bulb type is shown as LED for those positions.
The front turn signal bulb is listed as 7444NA. That same bulb number is also shown for the front parking light and front side marker light positions.
The rear turn signal bulb is listed as 7440. This is a separate fitment from the front turn signal bulb, so do not assume both ends use the same bulb number.
The back up reverse light bulb is listed as 7440. If you are replacing a reverse lamp, confirm the exact socket location before ordering.
No. The brake light bulb is listed as 7440R, while the back up reverse light bulb is listed as 7440. They are different fitments and should not be swapped without checking the chart.
The license plate light bulb is listed as LED. If you are replacing the license plate lamp, check whether your vehicle uses a complete LED unit or a serviceable bulb-style setup.
Common interior fitments listed on this page include the dome light, map light, glove box light, trunk or cargo area light, stepwell light, interior door light, and vanity mirror light. Several of these use specific bulb numbers such as 168, 917, 2721, 158, 74, and DE3022.
The vanity mirror light bulb is listed as 6615F. If your vanity mirror lamp is dim or out, match the bulb number carefully before replacing it.
Yes. The chart shows two floor console compartment light entries: one compared to original as option 1 with bulb 2721, and another compared to original as option 2 with bulb 74. This is a good example of why checking the installed bulb matters.
When a position is listed as LED, it usually means the lighting is handled by an LED source or LED assembly rather than a standard replaceable bulb number. In those cases, the exact service part may depend on the trim or lighting package.
Yes. That is the safest approach, especially for a model like the 2014 Acura MDX where trim and market differences can affect lighting equipment. Checking the installed bulb helps avoid ordering the wrong part.
