Parking lights remain on

With the engine off and the key out I found my parking lights were on when the headlight switch was off but slightly dimmer along with the instrument panel light. The fog lights work with this condition as well when the switch is activated. The main headlight switch still operates normally otherwise. I have had computer problems in the past with the engine cutting off and had replaced several times with a remanufactured one. Stll have had issues with this replacement but not since I hit slightly with a hammer...Yes this is another problem that I have had after much troubleshooting with the wiring harness and connections and hope this new problem is not related to the computer but I know the security system is linked to the computer that causes the lights to flash when activated. Till this problem is solved I will disconnect the negitive side of the battery.
