This 2009 Acura MDX bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right part the first time. Whether you are changing a headlight, a cabin light, or a rear marker lamp, this page is organized to make fitment checks simple and quick.

The 2009 Acura MDX uses a mix of halogen, HID, and LED lighting depending on the lamp location and equipment level. Because the exact setup can vary by trim, market, and body style, it is smart to match the bulb to the specific position on the vehicle instead of relying on a single size for the whole SUV.

For best results, compare the bulb listed here with the one already installed in your 2009 Acura MDX before buying replacements. Trim and package differences can affect fitment, especially on exterior lamps and interior convenience lights. Some positions may use halogen bulbs from the factory, while others may already be LED or HID, and aftermarket LED conversions can change beam pattern, brightness, and warning behavior. If you are upgrading from halogen to LED, make sure the new bulb physically fits the housing and is compatible with the socket and electrical system.

FAQ

What bulb fits the front fog lights on a 2009 Acura MDX?

Front fog light fitment can vary, but the listed options are H11 LED and H16 LED. Check the installed bulb and housing before ordering, since trim and market differences can affect the exact setup.

What size is the reverse light bulb on this MDX?

The back up reverse light bulb is 921. This is the bulb to verify if you are replacing the rear reverse lamps on a 2009 Acura MDX.

What bulb is used for the front turn signal?

The front turn signal bulb is 7440A. Make sure you match the bulb type exactly, since turn signal bulbs can differ from rear signal bulbs.

What bulb is listed for the rear turn signal?

The rear turn signal bulb is 7440. It is different from the front turn signal bulb, so check both sides separately if you are replacing rear signal lamps.

What are the license plate light bulb sizes?
