Bulb size chart
This page for the 2004 Acura MDX helps you verify the correct bulb size by lighting position, so you can match the right replacement before you buy. Whether you are replacing a burned-out headlight, a license plate lamp, or a reverse light, checking the bulb chart by location is the easiest way to avoid ordering the wrong part.
The 2004 Acura MDX uses different bulb types depending on where the lamp is installed, and some lighting details can vary by market, trim, or body style. Use the bulb list below to confirm the fit for the exact exterior or interior light you are servicing, especially if your MDX has a lighting package or has been modified over the years.
For best fitment, compare the bulb size on this page with the bulb already installed in your vehicle before purchasing, since trim and package differences can affect certain lights. Most positions on the 2004 Acura MDX were designed for halogen bulbs, so LED replacements may require a compatible design, proper beam pattern, or additional hardware to avoid glare, warning issues, or poor lighting performance. If your MDX has an aftermarket conversion or nonfactory housing, always verify the actual socket and bulb style at the lamp itself rather than relying only on the model year.
