This page covers bulb fitment for the 2017 Acura TLX and is organized by lighting position so you can quickly verify the correct bulb size for each exterior and interior lamp. Because trim level, lighting package, and market can change the equipment on this car, checking the bulb chart by location is the safest way to match the right replacement.

For the 2017 Acura TLX, many exterior lighting functions use LED assemblies, while several interior and utility lights still use replaceable bulbs. Use this page to compare the bulb type for headlights, tail lights, turn signals, license plate lights, dome lights, and other positions before you buy parts.

Fitment can vary between trims, packages, and body style, so always confirm what is installed on your specific TLX before ordering. Some lighting functions may be factory LED units that are not serviced with a simple bulb swap, while others may use a standard replaceable bulb. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, and physical clearance are compatible, and be aware that some conversions can affect beam pattern, brightness, or warning messages. The best practice is to inspect the existing bulb or housing first, then compare it with the bulb position listed on this page before purchase.

FAQ

What does this 2017 Acura TLX bulb page help me verify?

It helps you verify bulb sizes and bulb types by lighting position, such as headlight, fog light, brake light, license plate light, and interior lamps. That makes it easier to match the correct replacement for the exact location on the car.

Are all exterior lights on the 2017 Acura TLX replaceable bulbs?

No. Several exterior lighting positions on the 2017 Acura TLX are listed as LED assemblies. In those cases, the light may not use a traditional service bulb, so the whole unit or a specific service procedure may be required.

What bulb type is listed for the front turn signal on the 2017 Acura TLX?

The front turn signal light bulb is listed as 64132.

What bulb type is listed for the rear turn signal and back up reverse lights?

Both the rear turn signal light bulb and the back up reverse light bulb are listed as 7440.

What bulb is used for the vanity mirror light on this TLX?

The vanity mirror light bulb is listed as 6615F.

What bulb is used for the trunk or cargo area light?

The trunk or cargo area light uses 168 or 917, depending on the exact setup shown on the vehicle.

The glove box light bulb is listed as 2721.

What bulb is used for the interior door light?

The interior door light bulb is listed as 158.

Do trim levels affect bulb fitment on the 2017 Acura TLX?

Yes. Trim and lighting package can change the equipment on the car, so the exact bulb type or whether a lamp is LED can vary by market and body style.

Should I check the installed bulb before buying a replacement?

Yes. Checking the installed bulb is one of the best ways to avoid ordering the wrong part, especially when the car may have different lighting packages or factory LED units.

Can I replace a factory LED light with a standard bulb?

Usually not directly. Factory LED lighting often uses a sealed assembly or a different design than a standard bulb socket, so a simple bulb swap may not be possible.

What should I know before installing aftermarket LED bulbs in my TLX?

Make sure the replacement matches the socket, fits the housing, and works with the vehicle’s electrical system. Aftermarket LED bulbs can differ in brightness, beam pattern, and warning-light behavior, so it is smart to compare the installed bulb and test the fit before finishing the job.
