The 2018 Audi A7 is a luxury fastback with a mix of interior and exterior lighting locations that can vary by trim, market, and equipment package. This page is designed to help you verify bulb sizes by lighting position so you can match the correct replacement before you buy.
For this year and model, the listed bulb chart covers common fitment points such as the glove box light, interior door light, and front and rear side marker lights. Checking the bulb size by location is the easiest way to avoid ordering the wrong part for your 2018 Audi A7.
Fitment can differ depending on whether your A7 uses halogen or LED lighting in a given position, and some cars may have factory lighting packages that change the bulb type or eliminate a replaceable bulb altogether. Aftermarket conversions can also affect what fits, especially if a previous owner swapped housings or installed LED replacements. Before purchasing, it is smart to remove the installed bulb and compare it to the listing on this page, since the same model year may use different bulbs in different markets or body styles. If your car has already been modified, the bulb currently in the socket is the best reference for confirming the correct replacement.
