No such thing , tail lights get power from headlamp switch . When you turn on park or head lamps . tail lights light up . License plate lights come on as well as side marker lamps . Unless you thing of the turn signals an hazard lights . There is a flasher relay for that .
Turn/Hazard Flasher
At the left lower instrument panel, near the steering column

that line on that fuse is shorted, the fuse saved the fire.
we use an ampclamp DC ammeter to find the wire that is shorted
and the actual point of short.

the park-tail circuit (tail fuse, right) is the most complex of all.
20 lamps inside car, and many out side, it is the hardest to find of all shorts. but not with the tool
first check for damage behind all park lamps
i bet the fuse blows in park (1st click) not head lights. right?
side lamps the 4 front rear park lamps, some call it tail its not really tail now, was in 1920 ,not now. park is everywhere.
but the fuses can be marked tails, for fun .
imagine, calling the 2 front lamps tails. and are on .(my on going joke)
sidelamps,
the inside lamps are many too.
all dimmable lamps. so turn the dimmer down to zero and see if fuse blows now, NO?, bingo.

the best way to fix this is , visual inspections for collision damage or wire hacks in the cab.
then the fuse is pulled and circuit breaker inserted 15amp
(they sell em)
then we connent the ammeter to the wire (output of fues)
i push the switch and amps goes to infinity and the CB trips
if follow the cables, and find what line is shorted.

i missed one problem
on the rear or front 4 corners of the car may be twist lock blubs.
like 1157 or? these love to short. push in lamps never short.well not the lamp actual.
in not sure what lamps the 06 uses, but replace the brass based lamps. (in park tail ckt)

check the fuse panel on passenger side front feder well under hood and fuse panel in cab on drivers side

ok the full wiring is online, need that, a real FSM? for 1996 , same as 97
but not same 4sp tranny. i got confused, but seems the tail(parking) lamps are dead. you turn the Head lamps 1 click and some lights are dead.
there are a huge number if lamps in this circuit. Front and rear corners, all side lights x4, and dash maps, cig, lamp , ash tray lamp. radio lamp. shifter lamp (A/T) . and lic. plate.
for sure its wiring, if any lamp gloes, fully the HL (head light ) switch is good. so the wiring is bad to those lamps. the left rear has the trailer connector behind left rear Tail lens. see that. is it molested?
inspecting all 4 corners of care usually reveals collision damage , and
wires never repaired. you can use a volt meter to find this easy, have one?

Sounds like you need to replace the drivers brake/tail light.

check the wiring from the tailights back to the fuse panel, it sounds like an open connection. if i recall correctly check under the dash on the drivers side near the fuse panel for a bunch of wires in a bundle and look carefully for a wire or two that are cut/shorted/or seperated, you can also check under the drivers side kick panel by the hood release.

Try checking the headlight switch it may have broken contacts in it. Easy fix go to a salvage yard find same make and model truck, swap headlight switches.
