My backup lights don't work,so I replaced the bulbs and still not working.Also when I put my single lights on,the right,it cuts off after just a 1/4 of a turn

What is your question?

car was taking in for curise control,and it works ,but the single lights didn't work well,took it back and had to leave it,didn't have to pay extra,but althought the left works find,it's the right on that doesn't work right.When I played with the gear shft,the back-up lights comes on,but it willn't stay on.
