Acura TSX 2004 Bulb Size
Bulb size chart
This 2004 Acura TSX bulb guide helps you verify the correct bulb sizes by lighting position, so you can replace the right lamp the first time. Because bulb fitment can vary by trim, market, and body style, it is smart to match the bulb to the exact location on the car before ordering.
For the 2004 Acura TSX, the chart covers exterior, interior, and signal bulbs such as low beam, high beam, fog lights, brake lights, turn signals, license plate lights, and cabin lamps. Use the position-specific listings below to narrow down the correct replacement for your TSX and avoid mixing up similar-looking bulbs.
Fitment can differ between trims and lighting packages, especially on a model like the TSX that may have different equipment by market. Some positions use halogen bulbs, while others may be converted to LED by a previous owner, so the bulb currently installed may not always match the factory listing. If you are planning an aftermarket LED upgrade, check depth, connector style, and beam pattern before buying, since some housings are more sensitive to bulb shape and output. The safest approach is to inspect the installed bulb, compare the marking on the base, and confirm the position on the vehicle before purchase.
