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.
The headlight bulb for both high beam and low beam is listed as D1S on this page.
The front turn signal light bulb is 3757A.
The daytime running light bulb is 3757A, the same size listed for the front turn signal on this page.
The back up reverse light bulb is 3156.
The license plate light bulb is 2825, 98.
The parking light bulb is 2825, 98.
The front side marker light bulb is 2825, 98.
The front fog light bulb is listed as H11 LED or H16 LED.
Both the glove box light and stepwell light are listed as 194 or 7441.
The interior door light bulb is 561.
Courtesy light bulbs are listed as 561 for one option and 212-2 for another option, depending on the original setup.
Both the map light and engine compartment light are listed as 212-2.
The trunk or cargo area light is PC168.
This page lists the brake light bulb, tail light bulb, turn signal light rear, side marker light rear, and center high mount stop light as LED, so the exact replacement may depend on the lamp assembly used on your vehicle.
Because trim and lighting package differences can affect fitment, checking the installed bulb helps confirm the correct base, size, and style before you order.
