This page covers the bulb sizes for the 2003 Porsche 911 and helps you verify the correct bulb by lighting position. Because Porsche used different lighting setups across markets and body styles, it is important to match the bulb to the exact lamp location before ordering replacement parts.
Use the chart on this page to identify common exterior and interior bulbs for the 2003 911, including headlights, turn signals, brake lights, reverse lights, and cabin lights. Checking the position first makes it much easier to find the right fit and avoid buying the wrong bulb type.
Fitment can vary by trim, package, and lighting equipment, so a 2003 Porsche 911 may use different bulbs depending on whether it has halogen or HID headlights, or on the market it was sold in. Aftermarket LED conversions can also change the bulb you need, especially in exterior lamps where size, base style, and beam pattern matter. If you are unsure, remove the installed bulb and compare the markings before purchasing a replacement, since the same model year can use more than one bulb option in different positions.
The low beam bulb is D2S. This applies to the low beam headlight position on the 2003 Porsche 911.
With HID headlights, the high beam bulb is H11. Make sure your car actually has the HID setup before ordering.
With halogen headlights, the high beam bulb is H9. The high beam bulb depends on the headlight package installed on the car.
The front outer turn signal bulb is 2827.
The front inner turn signal bulb is 7507.
The rear turn signal bulb is 7507.
Both the brake light and tail light use 7528 bulbs on this model year.
The back up reverse light bulb is 7506.
The license plate light bulb is 6418.
The center high mount stop light bulb is 2821.
The front side marker light bulb can be 2825 or 98, depending on the exact lighting setup.
The front fog light bulb can be H3C or H3, depending on the car's equipment and market.
Interior and utility bulbs listed for this model include 6411 or 6428 for the trunk or cargo area light, dome light, and engine compartment light; 6428 for the glove box light; 2886X for the map light; and 2825 or 98 for the courtesy light.
Because trim, package, and market differences can change the bulb used in a specific position. Reading the bulb number from the installed part is the best way to confirm fitment before purchase.
