I had this problem with my 1994 Buick LeSabre and it no longer happened when I installed a new battery. It's been at least 6 months now with no recurrence of the problem.
Before the new battery, I noticed that if I waited about 5 minutes after turning off the car, I could get the lights to turn off. Seemed like something had to cool down.
Possible ground issue at the taillights.
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
my headlights work but my taillights and dash light dont work whats wrong
If you are referring to the brake lights it is probably a bad brake light switch. Your vehicle may also have daytime running lights which would be on without the parking lights.
in dash lights
GO AND BUY I NEW light bulb !
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 )
Many American cars in the 80s had horizontal taillights but no American car in the 80s had vertical headlights.
There is a fuse box under the hood (passenger side). I know the the fuses for the head lights are there. The fuse for the taillights is there and is labeled. This fuse includes the running lights but is not labeled as such.
headlights
Check your fuses. See owner's manual fo rlocation and identification of fuses.
Check the fuse for parking/tailights (dash lights also on this circuit)
