Just wired in new HD LED signal lamps. Already had LED tail light in place. Checked and rechecked wiring and installation. Problem is left signal extremely bright but works when left turn signal button pushed. Right signal light barely comes on and flashes very dimmly and very fast. Had previously installed module that illuminates signal lamps along with brake lamp when brakes applied. Is it possible that these new signal lamps are not compatible with that type of module or do I probably have a bad new signal lamp on right side. I know it is difficult to diagnose with this info, but help appreciated.

 

You don't need the module now.Remove it and see how they work.
