It sounds like an earthing problem. How do you have your new lights earthed? Doors sometimes do not earth very well. Is the battery earthed to the body with a good connection? Try clipping a wire from the battery earth terminal to the turn signal earth and see if this fixes the problem.

I recently purchased after market chevron turn signal lights that go on my existing side view mirrors. I wired the lights through the mirror through the door under the dash, then into the engine compartment where I tapped into the existing turn signal wires. The turn signals work fine, except when I turn on the headlights. When I turn on the headlights the mirror turn signals do not work. I have a mitsu montero sport 2002 and used 16guage wire to run the connection. Any thoughts or suggestions on fixing this is greatly appreciated.
