This 2023 Cadillac XT5 bulb size page helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. The XT5 uses a mix of LED exterior and interior lighting, and the exact fit can vary by trim, lighting package, market, and body style.
Use the bulb chart on this page to check common locations such as the low beam, high beam, fog light, daytime running light, tail light, brake light, turn signal, reverse light, license plate light, and cabin lamps. That makes it easier to replace a failed bulb or confirm what is installed on your specific XT5.
For best fitment, compare your vehicle’s trim and equipment with the bulb list before ordering. Some 2023 Cadillac XT5 models use factory LED assemblies in many exterior positions, while others may differ by market or package, so do not assume every bulb is the same across all versions. If you are considering an aftermarket LED conversion, make sure the bulb base, polarity, and physical clearance are compatible, especially in tight housings. When possible, remove the installed bulb first and check the part number or base type before purchase, since that is the most reliable way to avoid a mismatch.
The low beam headlight bulb is listed as LED on this page. Because the XT5 can vary by trim and lighting package, confirm the exact headlamp setup on your vehicle before buying replacement parts.
The high beam headlight bulb is listed as LED. If your XT5 has a different lighting package or market-specific headlamp design, verify the installed assembly before ordering.
The front fog light bulb is listed as LED. Many XT5 models use integrated LED fog lighting, so the replacement method may differ from a traditional replaceable halogen bulb.
The back up reverse light bulb is listed as 921. That is one of the few positions on this page with a specific replaceable bulb number.
The front turn signal light bulb is listed as 7440A. Always check the installed bulb and socket style, since some lighting packages may use different hardware.
The front side marker light bulb is listed as 194. This is a useful reference if you are replacing a burned-out marker or upgrading the appearance of the front lighting.
The license plate light bulb is listed as 2825. If one side is out, it is smart to replace both license plate bulbs at the same time for even brightness.
The vanity mirror light bulb is listed as 6612F. Check both sun visors if you want matching color and brightness.
The map light bulb is listed as DE3021. This is typically used for the overhead reading lights in the cabin.
Yes, the page lists the dome light, glove box light, trunk or cargo area light, and interior door light as LED. These are usually integrated interior LEDs rather than simple plug-in halogen bulbs.
The rear turn signal light bulb is listed as LED, and the rear side marker light bulb is also listed as LED. Because these are often part of a larger lamp assembly, replacement may involve the whole unit instead of a single bulb.
Yes, but fitment matters. Some positions are already LED from the factory, while others may use replaceable bulbs such as 921, 194, 7440A, 2825, 6612F, or DE3021. If you convert a halogen position to LED, check for polarity, error messages, beam pattern, and available space inside the housing.
