Using the right bulbs
Replacement bulbs are specified in the chart below. Headlamp bulbs must
be marked with an authorized “D.O.T.” for North America and an “E” for
Europe to ensure lamp performance, light brightness and pattern and safe
visibility. The correct bulbs will not damage the lamp assembly or void the
lamp assembly warranty and will provide quality bulb burn time.
