Headlamps

Aerodynamic

The headlamp system consists of:

• Two aerodynamic headlamps (13008) with replaceable halogen bulbs.
• Three-position headlamp switch (11654) (with integral circuit breaker).
• Headlamp dimmer switch (13A024) (part of turn signal and windshield wiper switch (13K359) ).
• Circuit wiring and circuit protection.

Power is supplied to the headlamp switch through Circuit 38 (BK/O) and 50A HD LPS fuse in the power distribution box and harness (14516) in the engine compartment. Ground is provided to the headlamps through Circuit 57 (BK).

Pulling the headlamp switch all the way out provides power to the headlamp dimmer switch in the turn signal and windshield wiper switch through Circuit 15 (R/Y).

• With the headlamp dimmer switch in the LO position (middle position), power is supplied to the low-beam elements through Circuit 13 (R/BK).
• With the headlamp dimmer switch in the HI position (forward detent), power is supplied to the high-beam elements through Circuit 12 (LG/BK) and to the high-beam indicator in the instrument panel (04320) .
• Momentarily pulling the headlamp dimmer switch toward the steering wheel (3600) closes the flash-to-pass switch and the high-beam headlamps light. They will remain lit until the headlamp dimmer switch is released.
