Bulb size chart

Whether you are replacing a front signal, a license plate lamp, or an interior courtesy light, matching the bulb to the correct position is the easiest way to avoid ordering the wrong part.
Because the MDX can vary by trim, market, and lighting package, the bulb chart on this page focuses on the positions commonly listed for this year. Use it as a fitment guide for the 2019 Acura MDX and compare the lighting position on your vehicle before buying replacement bulbs.
Fitment can differ between trims and body styles, especially when a vehicle is equipped with factory LED lighting or a specific appearance package. Some positions on the 2019 Acura MDX are LED assemblies rather than simple replaceable halogen bulbs, while others may use serviceable bulbs such as 7440, 7440R, 168/917, 2721, DE3022, 6615F, or 158 depending on the location. If you are considering an aftermarket conversion, confirm that the bulb type, connector, and housing depth will work with your vehicle, and check the installed bulb before purchasing whenever possible. This is especially important when a trim or market variation may change the exact fitment.
