My signal lights work fine until i turn on the headlights or park lights, when they are on the signals bleed to the opposite side. No matter which side I select the opposite side flashes lightly too. I replaced the flasher under dash and have checked all of the bulbs, fuses and sockets

Sounds like a bad ground at one of the lights. That or a short in the trailer wiring harness or rear light junction block.

Yep, as a man on an old list I frequent was fond of saying "Check the grounds". It is one of the major weak points on today's vehicles.
