Audi S4 2007 Bulb Size
Bulb size chart
This page helps you verify the bulb sizes for the 2007 Audi S4 by lighting position, so you can match the correct replacement before you buy. Because fitment can vary by market, body style, and lighting package, it is a practical reference for checking the bulbs used in the headlamps, interior lights, exterior markers, and cargo-area lamps.
For the 2007 Audi S4, the listed bulb types include D1S for the high beam and low beam headlight setup, 7506 for several signal and reverse functions, and 6418 or 6411/6428 sizes in multiple interior and utility locations. Use the position-specific listings on this page to narrow down the correct bulb for your exact light housing.
Before ordering, compare the bulb position on your car with the chart and confirm whether your S4 has a standard halogen-style replacement, an LED unit, or a factory HID setup, since trim and package differences can change the correct fitment. Aftermarket LED conversions may require additional adapters, resistors, or coding changes to avoid warning lights or uneven beam patterns. The safest approach is to inspect the installed bulb directly, especially for exterior lights and any lamp that may have been changed by a previous owner, before purchasing replacements.
