Acura ILX 2019 Bulb Size
Bulb size chart
This page helps you find the right bulb sizes for the 2019 Acura ILX by lighting position, so you can match the correct replacement before you buy. Because the ILX uses a mix of LED-equipped exterior lights and conventional interior bulbs, it is especially important to verify the exact location on the car rather than relying on one generic bulb listing.
Use the bulb chart on this 2019 Acura ILX page to compare the headlight, brake, turn signal, parking, reverse, license plate, dome, map, and other lamp positions. Trim and lighting package differences can affect fitment, so checking the bulb type by position is the best way to avoid ordering the wrong part.
For the 2019 Acura ILX, fitment can vary by trim, market, and body style, and some lighting functions may be LED from the factory while others use replaceable bulbs. That means a halogen-to-LED aftermarket conversion may not behave the same as the original setup, especially for beam pattern, warning messages, or compatibility with the housing. Before purchasing, it is smart to confirm the bulb already installed in your vehicle, compare it to the chart, and check whether your car has any optional lighting package differences that could change the correct replacement.
