Please check notes in each part listing to ensure the Side Marker Light Bulb is correct for your 1978 FIAT 131 with a 1.8L 1756cc 2BBL engine. WAGNER & DELCO or GE are competing brands, and each brand's Side Marker Light Bulb may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Side Marker Light Bulb fits only certain 1978 FIAT 131 models.
Clicking a "More Info" link will display a picture and/or other details about that Side Marker Light Bulb in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Side Marker 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 on "Find More Parts", to find more Electrical-Lamp & Socket parts, other FIAT 131 parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching. Both catalogs use the same shopping cart, so any auto parts you've already chosen for your 1978 FIAT will not be lost if you switch.
