Give etrailer an email.  explain your situation to a tech advisor. the new LED's are drawing less power than the OEM.https://www.etrailer.com/question-266207.html

The fast flashing of turn signals is caused by the flasher not having enough resistance. Need to change it out to an electronic flasher. Original flashers use amperage through a bi-metal device to open and close circuit. The electronic flashers has a circuit that causes the flasher to operate.
Verify your wiring to the new taillights. Ensure that the ground is ground, and taillights are taillights.
