Bulb size chart
This page helps you verify the bulb sizes for the 2004 Acura RSX by lighting position, so you can match the correct replacement before you buy. Because the RSX could be equipped with different trims, body styles, and lighting packages, checking the exact lamp location is the safest way to confirm fitment.
Use the bulb chart below to identify common exterior and interior bulbs on your 2004 Acura RSX, including headlights, tail lights, turn signals, reverse lights, map lights, dome lights, and more. Matching the bulb to the right position helps avoid buying the wrong size or the wrong base type.
Fitment can vary by trim, market, and whether your RSX has factory halogen lighting or an aftermarket LED conversion. Some positions may also use different bulbs depending on package or body style, so it is smart to compare the installed bulb before ordering. If you are upgrading to LED, make sure the replacement is compatible with the socket, polarity, and any warning-canceling needs, especially for exterior lights. For the most reliable result, remove the old bulb and check the markings on the glass or base before purchase.
