This 2017 Acura ILX bulb size guide helps you verify the correct bulb type by lighting position, so you can replace the right part the first time. Whether you are changing a headlight, a signal lamp, or a small interior bulb, matching the bulb to the exact location is the easiest way to avoid fitment mistakes.
The 2017 Acura ILX uses a mix of LED lighting and a few replaceable incandescent-style bulbs depending on the lamp and trim. Use this page to compare the bulb chart by function, including low beam, high beam, fog light, brake light, reverse light, license plate light, and interior lights such as the dome, map, and vanity mirror lamps.
Fitment can vary by trim, lighting package, body style, and market, so always confirm what is installed on your specific car before ordering. Some positions on the 2017 ILX are LED assemblies, while others use replaceable bulbs, and aftermarket LED conversions may require the correct base, polarity, or additional hardware to work properly. If you are unsure, remove the old bulb and compare it before purchase, especially for fog lights, reverse lights, and interior bulbs where multiple options may appear similar.
