I have a 1997 Toyota Rav 4. My parking lights come on after I press the brake.Y?

Turns out, as I took out the brake lamp (the one I replaced in the last few months) the situation no longer occurs. Could the wrong brake lamp/light be the offender? I need both brakes lights to work obviously.

Well surely it can't be something as simple as the wrong bulb, that is not nearly complicated enough!! Try a new bulb before you do anything else. The part # is 1157.

Changed the light bulb to the exact part number you described and it worked. I remember that number from buying it from a local auto parts store (this new one bought at Walmart). Weird that a light bulb would change the grounding but that's exactly what must have happened. THANKS FOR ALL YOUR INPUTS!

Actually it had nothing to do with the ground circuit. It simply provided a bridge from the brake lights over to park lights and vice versa, the ground circuit was/is working just fine!!! Always compare the bulbs, i.e. number of contacts closely befor replacing/installing as part numbers can be hard to find on the old bulb. Another great source for information about replacement bulbs and their part number is, the owners manual. We are glad you have it fixed!
