Acura MDX 2017 Bulb Size
Bulb size chart
Looking for bulb sizes for your 2017 Acura MDX? This page is designed to help you verify the correct bulb by lighting position, so you can match the right part before you buy. Whether you are replacing an exterior lamp or a small interior bulb, the goal is to make fitment easier and reduce guesswork.
The 2017 Acura MDX uses a mix of LED lighting and a few conventional bulb types depending on the location. That means the correct replacement can vary by function, and in some cases by trim or lighting package. Use the bulb chart on this page to confirm the bulb size for the exact light you need, from headlights and fog lights to cargo, glove box, and vanity mirror bulbs.
Fitment can vary by market, trim, and body style, so it is smart to confirm the bulb already installed in your vehicle before ordering. Some positions on the 2017 Acura MDX are LED-based and may not use a simple replaceable bulb, while others may have halogen-style or standard incandescent replacements. If you are considering an aftermarket LED conversion, check polarity, beam pattern, and housing compatibility so the new bulb works properly and does not create glare or warning issues. When possible, compare the old bulb, socket, and connector before purchase to avoid returns and make sure you get the right replacement the first time.
FAQ
What bulb sizes does the 2017 Acura MDX use for the headlights?
On this page, both the low beam and high beam headlight positions are listed as LED for the 2017 Acura MDX. That means the headlight assembly is not treated like a simple halogen bulb swap in the chart. Always confirm the exact lighting setup on your vehicle before ordering replacement parts.
Are the fog lights on the 2017 Acura MDX LED?
Yes, the fog light bulb position is listed as LED for the 2017 Acura MDX. Because LED fog lights are often part of a specific lamp assembly, replacement may involve more than just a standard bulb change. Check the installed setup before buying.
What is the rear turn signal bulb size for a 2017 Acura MDX?
The rear turn signal light bulb is listed as 7440 for the 2017 Acura MDX. This is a useful reference when replacing the rear signal lamps. Be sure to verify whether your vehicle has any market-specific lighting differences before ordering.
What bulb does the 2017 Acura MDX use for the reverse light?
The back up reverse light bulb is listed as 7440 for the 2017 Acura MDX. If you are replacing both sides, it is usually best to change them together so the light output stays even. Confirm the socket and bulb shape before purchase.
What is the brake light bulb size on this MDX?
The brake light bulb is listed as 7440R for the 2017 Acura MDX. This is separate from the rear turn signal and reverse light listings, so it is important not to mix the positions. Matching the correct bulb by function helps avoid fitment mistakes.
Does the 2017 Acura MDX use LED bulbs for interior lights too?
Several interior and cabin-related positions are listed as LED, including dome light, map light, floor console compartment light, door mirror illumination light, and stepwell light. However, not every interior bulb is LED, so check each location individually. The page is organized by lighting position to make that easier.
What bulb is used for the vanity mirror light?
The vanity mirror light bulb is listed as 6615F for the 2017 Acura MDX. This is one of the few interior positions on the page with a specific replaceable bulb number shown. Make sure the bulb matches the mirror lamp socket before installing.
What are the cargo area and glove box bulb options?
The trunk or cargo area light is listed as 168 or 917, and the glove box light has two comparison options listed: 2721 and 74. These notes indicate that fitment can vary, so checking the bulb already installed is especially important. Compare the old bulb to the chart before buying.
Are the side marker and parking lights LED on the 2017 Acura MDX?
Yes, the front side marker, rear side marker, and parking light positions are listed as LED for the 2017 Acura MDX. Since these may be integrated into the lamp assembly, replacement can differ from a standard bulb swap. Verify the exact lamp design on your vehicle.
Can trim level or lighting package change the bulb fitment?
Yes. Trim and lighting package can vary by market and body style, and that can affect bulb fitment on the 2017 Acura MDX. Even when the chart lists a bulb size, it is still wise to confirm the installed part in your vehicle before ordering.
What should I check before replacing a bulb on my 2017 Acura MDX?
Check the bulb position, the socket type, and whether the lamp is LED or a replaceable bulb. For the 2017 Acura MDX, some locations are LED while others use standard bulb numbers like 7440, 7440R, 6615F, 168/917, 2721, 74, or 158. Matching the exact position is the safest way to get the right part.
Why does this page list bulb sizes by lighting position instead of one size for the whole vehicle?
Because the 2017 Acura MDX uses different bulb types for different lights. Headlights, fog lights, turn signals, license plate lights, interior lamps, and cargo lights do not all use the same part. Listing by position helps you verify the correct bulb size for the exact lamp you are replacing.
