Cadillac XLR 2008 Bulb Size
Bulb size chart
This 2008 Cadillac XLR bulb size guide helps you verify the correct bulbs by lighting position, so you can match the right part before you buy. The XLR uses a mix of LED and conventional bulb types, and the correct fit can depend on where the bulb is installed.
Use this page as a quick reference for exterior and interior lighting on the 2008 Cadillac XLR. It covers common replacement points such as headlights, fog lights, turn signals, brake lights, license plate lights, courtesy lights, and cargo-area lighting.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm the bulb already installed in your XLR before ordering. Some positions use LED assemblies, while others use replaceable halogen or incandescent-style bulbs, and aftermarket LED conversions may need the correct base size, polarity, or load correction to work properly. If your car has been modified, or if a previous owner changed a bulb type, the installed bulb may not match the original listing. Checking the old bulb and comparing it with the socket is the safest way to avoid returns and ensure proper brightness, beam pattern, and warning-light behavior.
