Lightning models have two headlamps. Only one headlamp is illuminated during low or high beam operation. See a Buell dealer for replacement headlamp bulbs. See a service manual for the headlamp aiming procedure.
The automatic-on headlamp feature provides increased visibility of the rider to other motorists. Be sure headlamp is on at all times. Poor visibility of rider to other motorists can result in death or serious injury. (00030b)
See Figure 1. XB9SX and XB12STT models have a headlamp grille to provide additional protection for the headlamp assembly. When spreading the headlamp grill during removal/installation be careful not to spread the grill too far. If this happens simply compress the grille until it fits snugly on the headlamp assembly.
