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 assure 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.
