For some reason the only time that my rear lights work is when my high bbeams are on?  When I turn the car on and the low beams are on the rear lights dont turn on as well?  Why is that.

ok 2 things does your blinkers and brake lights work if yes . then you have what they call day time running lights which will turn on the headlights but not the tail lights when you start the car . make sure the main switch is on
