Please check notes in each part listing to ensure the License Plate Lamp Bulb is correct for your 2003 CADILLAC DEVILLE with a 4.6L engine. WAGNER & ACDELCO are competing brands, and each brand's License Plate Lamp Bulb may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a License Plate Lamp Bulb fits only certain 2003 CADILLAC DEVILLE models.
Clicking a "More Info" link will display a picture and/or other details about that License Plate Lamp Bulb in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a License Plate Lamp Bulb, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Electrical-Lamp & Socket parts, other CADILLAC DEVILLE parts or parts for a different vehicle.

Both catalogs use the same shopping cart so any auto parts you've already chosen for your 2003 CADILLAC will not be lost if you switch.
