Cadillac XLR 2009 Bulb Size
Bulb size chart
This 2009 Cadillac XLR bulb guide helps you verify the correct bulb sizes by lighting position, so you can match the right replacement to the exact lamp on the car. Whether you are replacing a headlight, license plate light, or interior courtesy bulb, using the correct location on the page makes fitment much easier.
The 2009 Cadillac XLR uses a mix of LED, halogen, and standard bulb types depending on the lamp position. Because front and rear lighting can differ, this page is organized to help you confirm each bulb size before you buy replacements.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to compare the listed bulb size with the bulb already installed in your XLR before ordering. Some positions may use LED assemblies while others use replaceable bulbs, and aftermarket LED conversions can change the required fitment or trigger compatibility issues. If you are upgrading from halogen to LED, check the socket type, beam pattern, and any resistor or CAN-bus needs before installation. The safest approach is to inspect the existing bulb, confirm the base and wattage style, and then purchase the closest match for your specific vehicle.
