Got home last night and the parking lights stay on. I even pulled the fuse but the lights still stay on. Now I have to unhook the battery cable. Any help?

What year is your Camry?
Some model years have a lamp control module that controls exterior lighting.
And, which fuse did you pull?

Thanks, it is a '91 camry. Started to do this last night. Pulled the 15 amp fuse under the dash. The manual said that was the fuse for the parking lights, which stay on.

Even if the tail lamp relay were stuck in the on position, if you pulled the Tail Lamp fuse, the park lamps should go off.
Make certain that you are in fact pulling the TAIL Lamp fuse. Also, check the Tail Lamp relay for being stuck on.

If that's not faulty, check for a shorted lamp switch

1994 Subaru Legacy tail lights and clearance lights stay on all the time. Is there a relay that may be stuck?

I had similar symptoms on a 2.2L 4-cyl 1992 Camry XLE, dash and parking lights on front and rear staying on after headlights go out, and figured there was a relay sticking on. To keep from draining the battery I pulled the fuse and put it back in whenever needing to drive at night.

The taillight relay on my '92 Camry is located on the rear of the driver-side fuse panel, behind the coin tray. It is very difficult to access and you'll need a small screwdriver, flashlight, and mirror to get to it. I came in from the passenger side and lay across the two seats on my bacak with my head on the floor. Looking in the mirror you can see three identical blue relays on the back of the fuse panel. The closest one is the Defogger Relay. Directly above and offset towards the passenger side is the Taillight Relay, and further towards the passenger side is the Power Main Relay.

There is not enough clearance to get your fingers around the Taillight Relay, and using channel-lock pliers only pulls the blue cover off. I finally got it out by first removing the Defogger Relay by prying it from the bottom with the screwdriver. Once it is out of the way then I was able to get the screwdriver under the base of it and prying against the Defogger Relay socket.

I've ordered a replacement part ($27 at OReilly's) and will see if that solves the problem.
