Acura TSX 2006 Bulb Size

Bulb size chart

The 2006 Acura TSX uses several different bulb types depending on the lighting position, so this page is designed to help you verify the correct bulb size before you buy replacements. Whether you are changing a headlight, interior lamp, or exterior marker light, checking by location is the easiest way to match the right fit for your TSX.

Because trim and lighting package can vary by market and body style, the bulb chart for the 2006 Acura TSX is organized by function rather than by a single universal part number. That makes it easier to find the right bulb for the exact light you are servicing, from low beams and fog lights to dome, map, and license plate lights.

For best fitment, compare the bulb listed here with the one already installed in your vehicle before ordering, especially if your TSX has been modified or uses aftermarket lighting. Some positions may work with halogen or LED replacements, but the original equipment style, connector shape, and bulb base still need to match. If you are converting from halogen to LED, check beam pattern, polarity, and space inside the housing so the new bulb fits and performs correctly. This is especially important for headlights, fog lights, and exterior signal lamps, where improper conversions can cause glare or warning issues.
