Audi Q3 2019 Bulb Size
Bulb size chart
The 2019 Audi Q3 uses a mix of LED lighting positions, and this page is designed to help you verify bulb sizes by location before you buy anything. Whether you are replacing a front signal, a license plate lamp, or a rear brake light, matching the bulb to the correct lighting position is the safest way to avoid fitment mistakes.
Because trim and lighting equipment can vary by market and body style, the exact bulb setup on a 2019 Audi Q3 may not be identical on every vehicle. Use the bulb chart on this page as a position-by-position reference for the most common exterior and interior lighting points, including headlights, daytime running lights, tail lights, markers, and the stepwell light.
For best results, compare your vehicle’s installed bulb and housing type before ordering, especially if your Q3 has a different trim level or lighting package than another model year or region. Some vehicles use LED modules where others may have serviceable bulbs, and aftermarket LED conversions can change fitment, beam pattern, or warning behavior. If you are unsure, remove the existing bulb or inspect the lamp assembly first so you can confirm the correct replacement before purchase.
FAQ
What bulbs are listed for the 2019 Audi Q3 on this page?
This page includes bulb positions such as the high beam headlight, low beam headlight, daytime running light, parking light, front and rear turn signals, brake light, tail light, license plate light, back up reverse light, side marker lights, center high mount stop light, and stepwell light.
Does every 2019 Audi Q3 use the same bulb setup?
Not always. Trim level, lighting package, market, and body style can affect which bulbs or LED modules are installed. Always verify the exact lighting position on your specific Q3 before buying replacements.
Are the headlights on the 2019 Audi Q3 halogen or LED?
The available bulb chart for this page shows LED for the headlight high beam and low beam positions. However, equipment can vary by market and package, so it is still smart to confirm the installed setup on your vehicle.
Can I replace a single LED bulb on the 2019 Audi Q3?
Sometimes yes, but not always. Some LED lighting positions use serviceable bulbs, while others may be part of a sealed LED module or assembly. Check the specific lamp location before ordering a replacement.
How do I find the correct bulb for the license plate light?
Use the bulb chart entry for the license plate light bulb and compare it with the bulb installed in your vehicle. The 2019 Audi Q3 page is organized by lighting position so you can match the correct lamp more easily.
What should I check before replacing a rear turn signal bulb?
Confirm whether your rear turn signal uses a replaceable LED bulb or an integrated LED unit, and make sure you are looking at the correct side of the vehicle. Rear lamp designs can differ by trim and market.
Are front and rear side marker bulbs the same on the 2019 Audi Q3?
They may not be the same, even though both are listed on the page. Front and rear side marker lights are separate positions, so verify each one individually before ordering.
Can I use aftermarket LED bulbs in place of the original bulbs?
Aftermarket LED conversions may fit physically, but they can also affect brightness, beam pattern, or warning messages. If you choose an LED upgrade, make sure it is compatible with the lamp housing and electrical system on your Q3.
What is the best way to confirm bulb fitment on my 2019 Audi Q3?
The most reliable method is to inspect the installed bulb or lamp assembly and match it to the bulb position listed on this page. This is especially important if your Q3 has a different lighting package than another vehicle of the same year.
Does the center high mount stop light use a standard bulb?
The page lists the center high mount stop light bulb as LED. Because LED stop lamps can be integrated into the assembly, check the actual unit on your vehicle before purchasing any replacement part.
Why is it important to verify bulb size by lighting position?
Different lighting positions on the same vehicle can use different bulb types or LED assemblies. Verifying by position helps you avoid ordering the wrong part for the headlight, tail light, brake light, signal, or interior stepwell lamp.
What if my 2019 Audi Q3 has a lighting package not shown here?
If your Q3 has a special trim or lighting package, compare the installed parts to the chart and confirm the exact lamp design. When in doubt, check the bulb directly or consult the vehicle’s lighting assembly before buying replacements.
