The electrical system will handle the load from trailer lights but you should use a 30 amp relay. Don't tap directly to your taillight wiring without a relay. You don't want any more load on your ignition switch. Run power wire direct from battery and use your taillight wire to trip the relay.
I guess I need more than that. Unplugged bike lights are fine. Plugged to Trailer and no blinkers, no running lights (except on Trailer Bumper), BRAKE LIGHTS WORK ON BOTH. Back of bike is not working accept brakes. Unplug and all goes back to normal. No fuses tripped.
