Getting the bulb sizes for a specific model can be a bit tricky, so to help you in that research, you will find the correct bulb sizes for your Acura MDX. That way, you will know you are making the correct replacements.

Why should you replace the bulbs on your Acura MDX?

There are two main reasons: upgrading them and replacing broken ones.

Bulbs, regardless if they are halogen or HID, both have a limited lifespan, meaning that once they stop working, you will need to replace them. The exterior lights on your car play a considerable role in illuminating your path or signal other cars, and it is essential to replace them if they are not working.

On the upgrading side of things, owners often want to improve the look on their cars, and that is the second reason for replacing the bulbs on your MDX. Newer LED bulbs will give your car a newer look and enable you to have something you did not have when you purchased it.

Upsides to upgrading bulbs to LED

LED technology has improved over the past decade, so not it offers a lot of advantages over the traditional halogen or HID bulbs.

The most common and highly praised advantage that LED bulbs offer is how long they last. Halogen or HID bulbs can last several thousand hours, rarely going over ten thousand. LED bulbs, on the other hand, can work for 50 thousand hours and sometimes even more.

Longevity aside, LEDs also consume much less power than the traditional bulbs that would be already installed. It may not mean much to you, but since the bulbs are powered by the alternator, introducing low power bulbs means that it will need less energy to power them.

Procedure for replacing a headlight bulb on an Acura MDX

To ensure that you do not make any mistakes disconnect the car battery before you proceed.

On the back of the headlight assembly, there is a plastic cap that you need to unscrew to open it up. Below that, you will see the connector plugged in the back of the bulb. Unplug that, and you will see the bulb and the metal pin holding it in place. Release the pin, and the bulb will be released. Put the new bulb in the slot and tighten the pin in place.

Do the second and third-generation MDX have the same bulbs?

They may share some of the bulbs, but not all of them will be the same.
