The 2019 Audi Q5 uses different bulb types depending on the lighting position, so the safest way to replace a failed lamp is to match the bulb by location rather than by appearance alone. This page helps you verify the correct bulb size for each exterior and interior light on the 2019 Audi Q5, including headlamps, tail lamps, turn signals, reverse lights, and cabin lighting.
Because Audi offered the Q5 with different lighting packages, the bulb list can change with trim, market, and body style. On this page, you can quickly check the bulb size for each position before ordering parts, which helps avoid returns and makes replacement work much easier.
Fitment on the 2019 Audi Q5 can vary by trim and lighting package, especially when comparing halogen, HID, and LED-equipped vehicles. Some bulbs are part of factory LED modules, while others use replaceable service bulbs such as the 921 reverse light, 921 rear fog light, 2825/98 glove box light, 64132 front turn signal on HID headlight models, and D5S headlight bulbs on HID setups. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, physical length, and heat management all match the original application. The best practice is to inspect the bulb already installed in your vehicle before buying replacements, since Audi may use different parts depending on options and production details.
