Please check notes in each part listing to ensure the Radio Dial Light Bulb is correct for your 1990 GMC C3500 PICKUP with a 7.4L 454 engine. WAGNER & GE are competing brands, and each brand's Radio Dial Light Bulb may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Radio Dial Light Bulb fits only certain 1990 GMC C3500 PICKUP models.
Clicking a "More Info" link will display a picture and/or other details about that Radio Dial Light Bulb in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Radio Dial Light 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 GMC C3500 PICKUP parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1990 GMC will not be lost if you switch.
