BULB REPLACEMENT
Headlamp Condensation
The headlamps are vented to equalize pressure. When moist air enters
the headlamp(s) through the vents, there is a possibility that
condensation can occur. This condensation is normal and will clear
within 45 minutes of headlamp operation.
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.
