1. A lighting system for a towed vehicle which is adapted to be connected to a towing vehicle, said lighting system comprising:

  • a first conductor for receiving a right hazard signal from the towing vehicle;

    a right hazard lamp connected to the first conductor for energizing by the right hazard signal;

    a second conductor for receiving a left hazard signal from the towing vehicle;

    a left hazard lamp connected to the second conductor for energizing by the left hazard signal;

    a right turn indicator lamp;

    a first switch selectively connecting the right turn indicator lamp to the first conductor;

    a left turn indicator lamp;

    a second switch selectively connecting the left turn indicator lamp to the second conductor;

    a control circuit having inputs coupled to the first conductor and the second conductor, and having outputs connected to the first switch and the second switch, the control circuit responding to the first and left hazard signals changing states substantially in synchronism by rendering the first switch and the second switch nonconductive, and responding to the first and left hazard signals changing states asynchronously by rendering the first switch and the second switch conductive.
