Since the brake light and turn signal are still functioning, just are dim, it does sound like a connection issue. I recommend checking the ground for corrosion or rust and just cleaning it up and if that doesn't solve your issue, then put a circuit tester like # PTW2993 on it. The incandescent bulb in the tester should show a difference, so if it does or doesn't you have isolated which wiring needs to be checked for a short and replaced. Normally light wiring is # 16-1-1 wire.
