Headlights Circuit Description Chevrolet

When the headlamp switch is in the HEAD position voltage is applied through circuit 10 /12 to the headlamp dimmer switch and the right and left low beam headlamp. Ground is always applied to the headlamps through circuit 150 (left) or 250 (right). When the voltage is applied through circuit 12, the low beam headlamps turn on.

When the headlamp dimmer switch is moved to the HIGH position, voltage is also applied through circuit 11 to the right and left high beam headlamps turning them on. When the dimmer switch is in the HIGH position voltage is also applied to the instrument cluster through circuit 11 turning the HIGH BEAM indicator on. Ground is applied to the instrument cluster at all times through circuit 650.

Headlights Circuit Description Pontiac

When the headlamp switch is in the HEAD position voltage is applied through circuit 10 to the headlamp dimmer switch. When the dimmer switch is in the LOW position, voltage is applied through circuit 12 to the right and left low beam headlamp. Ground is always applied to the headlamps through circuit 150 (left) or 250 (right). When the voltage is applied through circuit 12, the low beam headlamps turn on.

When the headlamp dimmer switch is moved to the HIGH position, voltage is no longer applied through circuit 12 and the low beam headlamps turn off. Voltage is now applied through circuit 11 to the right and left high beam headlamps turning them on. When the dimmer switch is in the HIGH position, voltage is also applied to the instrument cluster through circuit 11 turning the HIGH BEAM indicator on. Ground is applied to the instrument cluster at all times through circuit 650.
