A Honda CRV is right at the line for needing supplemental breaks - about 3500 lbs. Check out the ready break. As for lights, get a 4 wire setup and use the magnetic trailer lights on the back of the vehicle - separate from the car. A bounder for sure is wired for a trailer - maybe it was modified? I assume your vehicle can be towed 4 down.
