Headlight/tail light defective warning symbol and tone come on when braking
What is your question?
Everytime the brakes are applied the warning symbol/tone comes on. The brake lights appear to work fine with the exception that the brake light on the hatch comes on with the headlights. The tone/warning light began when the rear undercarriage struck the lip of a ditch I was going over. Did find the rt side brake light bulb was seperated and changed it out. The tone is annoying as hell and I would like to disable it temporarily until this lighting issud is fixed.

From your description, it sounds as if you may have damaged part of the lighting wiring harness. When a wiring harness gets damaged, it causes all sorts of issues because the wiring goes through modules causing adverse effects. The best thing to do would be to inspect and repair whatever damage is there and go from there. Any qualified repair shop should be able to get this rectified for you. Hopefully that helps.
It sounds like you have a single element bulb (1156) in place of the dual element (1157) in one of your brake/park light sockets. This will cause power to feed back (with the park lights on) to the light module through the brake circuit and trigger a failure warning. When you hit the brakes power is sent through the park light circuit. As for the ever since you hit the ditch you may have damaged trailer wiring, if equipped. That would be the only wiring that susceptible to damage under the vehicle related to the brakes. I would start by verifying that the RT brake light has the correct bulb.
