Acura TSX 2005 Bulb Size
Bulb size chart
This 2005 Acura TSX bulb size guide helps you verify the correct replacement bulb by lighting position, so you can match the right part before you buy. Whether you are replacing a headlight, turn signal, brake light, or small exterior marker lamp, checking the bulb chart by location is the easiest way to avoid fitment mistakes.
The 2005 Acura TSX uses several different bulb types depending on where the light is mounted, and some positions may vary by trim, market, or body style. Use this page as a quick reference for the most common exterior bulbs on the TSX, including headlight, fog light, parking light, license plate light, and rear lamp positions.
For best results, confirm the bulb type on the vehicle before ordering, especially if your TSX has a different trim or lighting package than another 2005 model. Some positions may use halogen bulbs, while others may be part of an HID or LED aftermarket conversion, and those changes can affect what fits correctly. If a previous owner upgraded the lighting, the installed bulb may not match the original factory listing, so it is smart to inspect the old bulb and connector before purchasing replacements. This is especially important for fog lights and headlight conversions, where aftermarket parts can change the required fitment.
