There are some certain demands for cars with motor FXJA and year of production 2004. Usually lamps in 1.4 engine vehicles made by Ford live quite long. The important feature to look at when buying bulbs for Ford is voltage at 12 V. Choose only recommended size and shape of lamp for Fusion 1.4 made in 2005 if you want to replace whole thing. You also need to ensure 21 W of power for cars produced in 2007. The only possible base type for Fusion signals is Bau15S. All owners of Ford Fusion should control turn signal work.
You may check if Ford Fusion turn light works by just changing the lamp. It’s better to buy Bau15S base lamp to ensure that lights in 2010 Ford Fusion work properly. One of destroying factors is over 12 V voltage lamp and bulbs having more capacity than 21 W. It won’t help your 1.4 motor car with code FXJA to save normal light work.
