Acura MDX 2014 Bulb Size
Bulb size chart
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.
FAQ
What does this 2014 Acura MDX bulb size page help me confirm?
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.
Are the headlight bulbs on the 2014 Acura MDX listed as LED?

What bulb is used for the rear turn signal on the 2014 Acura MDX?
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 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.

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.
Why do some bulb positions show LED instead of a bulb number?
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.
Should I verify the installed bulb before buying replacements for the 2014 Acura MDX?
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.
