If you have no brake lights or tail lights then you've probably got an electrical problem. Check the fuses first and see if you have one or more blown.
in dash lights
Is it the taillights or the brake lights? If taillights it may be a wiring problem, If brake lights check the switch on the brake pedal
Check the switch.
Possible ground issue at the taillights.
I'm not a mechanic / technician but I would assume that would be your headlight switch ( I lost my headlights , taillights , and dash lights on my 1971 Mustang one night while travelling on a highway , pretty dangerous )
my headlights work but my taillights and dash light dont work whats wrong
Start by checking your fuses. Then bulbs. Then switches in that order.
The bulbs should be checked on a 1993 Dodge Dakota if the taillights are not working. The plugs on the trailer package should also be checked to make sure that they are working.
sound like a short in the headlamp switch.....I had a similar problem in my 98 chrys sebring...I took off the headlamp/turn signal switch and found a broken wire.....headlights and turn signals worked...taillights didn't...........
it may be your headlight switch, all mentioned circuits are routed through it
the circuit boards on the taillights are bad.
Many American cars in the 80s had horizontal taillights but no American car in the 80s had vertical headlights.
