Sounds like the contacts are welding shut (closed). Can you try running without either light to see which one is causing the issue? Also, are you sure there isn't another relay downstream? Voltage collapsing on a coil will cause back EMF, a diode in parallel with that coil will help protect any contacts feeding the coil.
