Sounds like you have a short or other wiring
problem. A common area of odd electrical
problems for rear lights is the circuit boards in the
rear assemblies that the bulbs plug into.
Sometimes they short out internally, and cause
back feeding into other lighting circuits. Also, look
into the plug for both of those circuits, and look for
This assuming that all bulbs ARE good. The
incorrect bulbs, or bent terminals on the bottom of
the bulbs can also cause this sort of back feeding.
Turn signal switch is also a possibility, but those
rear circuit boards are usually the cause.
