If the lights on your trailer were acting fine prior to installing the LEDs then you need to start off by checking the ground connections for your lighting. Make sure they are securely connected to a clean, bare-metal surface as even some paint can cause issues.
If that doesn't fix your problem then the solution to your issue is to add load-resistors. I recommend the Diamond # DI34ZR.
Since LEDs draw less power than incandescent lights it is not uncommon to have to install load-resistors so that the tow vehicle knows to send power back to those tail lights.
