2002 Acura RSX bulb fitment starts with H1 bulbs for both the low-beam and high-beam headlights. The daytime running lights also use H1 bulbs, so verify the intended lighting position before ordering replacements.
For the fog lights, the supplied fitment lists either an H11 LED or H16 LED option. Confirm the socket and lamp configuration on your RSX before purchase, as these are listed as alternatives rather than a combined application.

- Rear side-marker light: 168NA

Use the existing bulb base and vehicle socket to confirm the listed size, particularly for the fog-light and license-plate alternatives.
