Acura NSX 1999 Bulb Size
Bulb size chart
This 1999 Acura NSX bulb size guide helps you verify the correct replacement bulbs by lighting position, so you can match the right bulb to the right socket before you buy. Whether you are replacing exterior lamps, dashboard indicators, or small interior lights, this page organizes the common bulb sizes for the NSX in one place.
Because trim and lighting equipment can vary by market and body style, it is always smart to compare the bulb chart with the bulbs already installed on your car. Use this guide as a reference for the 1999 Acura NSX, then confirm the fitment at each lamp location for the best results.
Fitment can differ between standard halogen setups, factory options, and aftermarket LED conversions, so do not assume every NSX uses the same bulb in every position. Some owners may find that a previous repair or conversion changed the bulb type, especially in exterior lamps and interior courtesy lights. Before ordering, check the installed bulb, the socket, and the lens area for any markings or adapter hardware. If you are upgrading to LED, make sure the replacement is compatible with the vehicle’s electrical system and that the beam pattern, polarity, and warning behavior are acceptable for the application. When in doubt, compare both the chart and the original bulb before purchase.
