1. A tail light converter configured to operate the lights of a trailer using input signals supplied by lighting circuits of a towing vehicle to provide outputs to the trailer lights:
a tail light converter circuit comprising;
a first electromagnetic relay having:
normally closed switch contacts comprising two switch contact terminals, and an energizing coil comprising an input terminal and ground terminal connections, wherein the first electromagnetic relay having a first switch contact is electrically connected to a side of the towing vehicle turn supply circuit; the first electromagnetic relay having a second switch contact is electrically connected to the corresponding trailer turn/brake supply circuit; the coil input terminal of the first electromagnetic relay is electrically connected to a vehicle brake supply circuit; the coil output terminal of the first electromagnetic relay is electrically connected to ground;
a second electromagnetic relay having:
normally closed switch contacts comprising two switch contact terminals, and an energizing coil having an input terminal and ground terminal connections, wherein the second electromagnetic relay having a first switch contact is electrically connected to the vehicle brake supply circuit; the second electromagnetic relay having a second switch contact is electrically connected to the trailer turn/brake supply circuit corresponding to the first electromagnetic relay second switch contact; the coil input terminal of the second electromagnetic relay is electrically connected to the vehicle turn supply circuit corresponding with the first electromagnetic relay first switch contact; the coil output terminal of the second electromagnetic relay is electrically connected to the opposite side vehicle turn supply circuit; and
a high resistance system circuit comprising:
an electronic switch including: two switch contacts and a control, wherein the electronic switch having a first switch contact is electrically connected to the coil output of the second electromagnetic relay; the electronic switch having a second switch contact is electrically connected to the ground; the electronic switch control is electrically connected to the ground; the electronic switch control is electrically connected to the opposite side of the vehicle turn supply.
