Tail Lamp: Description and Operation

When the headlamp switch is moved to the PARK or ON position, battery voltage is applied through CKT 9 to the Left Instrument Panel Fuse Block (LIPFB). Battery power passes through the LIPFB to both license lamps, both tail lamps, both front park/turn lamps, both rear tail lamps, and all marker lamps through CKT 9. The front marker and front park/turn lamps are grounded by CKT 150 through the forward lamp ground splice pack.
