It could be as simple as bulbs burned out or your switch could be defective.

There are a number of reasons why your parking lights won't turn off. There could be a wiring problem in the system.
Of course.
check for short to power in the circuit
Check the adjustment of the brake light switch.
Check the headlite switch.
Check your fuses
Do the dash lights come on now that you have put in a new fuse...Does the motor rotate or try to turn over....If not, it sounds like you have a bad ignition switch....
on the back of the car
On my 1996 suburu there is a switch on the top of the steering wheel/column that is a toggle for the parking lights on/off. I accidentally hit it one day while cleaning my car and it took me hours to figure out how to turn the parking lights off...oops that lil switch i never touch got bumped and i didnt realize it.
What i did on mine was bought some electrical grease, greased all the contact at the lights and have not had a problem with it since, that was five years ago.
i have volvo v70 2001 she has abs lights come one for the last six weeks now my car wont start at all can the abs cause some think like that. thanks
