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.
FAQ
What bulbs are listed for the 2019 Acura ILX headlights?
The chart shows LED-based headlight listings for the 2019 Acura ILX, including High Beam and Low Beam LED entries. Some rows separate the high beam and low beam functions, while another row combines them, so it is important to match the exact headlight position on your car.
Does the 2019 Acura ILX use replaceable bulbs for every exterior light?
No. Several exterior lighting functions on the 2019 Acura ILX are listed as LED, which often means the light source is integrated rather than a simple plug-in bulb. Other positions, such as the back up reverse light and some marker or interior lights, use replaceable bulb types.

The back up reverse light bulb is listed as 921 for the 2019 Acura ILX.

Are the map light and glove box light the same bulb type?
Both the map light and glove box light are listed as LED on this page, but they are separate lighting positions and should be checked individually before replacement.
Why does the bulb chart mention trim and lighting package differences?
Because the 2019 Acura ILX can vary by trim, market, and package, the exact bulb setup may not be identical on every vehicle. The chart helps you verify the bulb by location so you can match the correct fitment for your specific ILX.
Can I replace an LED factory light with a standard halogen bulb?
Usually no. If your 2019 Acura ILX came with an LED factory light for that position, a standard halogen bulb will not be a direct replacement. You should match the original design or use a compatible LED solution designed for that housing.
What should I check before ordering bulbs for my 2019 Acura ILX?
Check the bulb position, confirm the bulb already installed in the vehicle, and compare it to the chart on this page. It is also helpful to verify whether your ILX has optional lighting equipment or a different trim package that changes the bulb type.
