Acura RSX 2006 Bulb Size
Bulb size chart
This 2006 Acura RSX bulb size guide helps you verify the correct bulbs by lighting position, so you can replace the right lamp without guesswork. Whether you are changing a headlight, interior bulb, or exterior signal light, matching the bulb to the correct location is the easiest way to avoid fitment mistakes.
Use this page as a quick reference for the 2006 Acura RSX lighting layout. The RSX can use different bulb types depending on trim, market, and body style, so it is smart to confirm the bulb position before ordering replacements.
For best results, compare the listed bulb type with the bulb already installed in your RSX before you buy. Trim and package differences can affect fitment, and some owners switch from halogen to LED bulbs for brighter output or a different color temperature. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, and housing clearance are compatible, especially in tight locations like the map lights, license plate lights, and headlight assemblies. When possible, check the existing bulb markings or remove one bulb to confirm the exact match before purchasing a full set.
