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 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.
