I would begin by making sure each marker light has a good ground connection to a clean metal surface. Each light should be grounded to a rust-free, metal surface. If the ground is achieved through the metal base of the light, there may be corrosion or rust that has formed which is causing a bad ground.

I would also recommend checking the power supply to the lights, you can do so with a circuit tester like part # PTW2993. You will want to inspect the wiring making sure there is not a short or exposed wiring.
