Are the relays on a 94 1500 heavy enough to run a trailer withLED lights?

I would suggest using a wiring isolator that powers off your battery. That way if the trailer shorts it will not mess up the bikes electrical system.

Yes it will handle the LEDs but either fuse the lights with a 2 amp fuse on each or get an isolator as mentioned above.

Where is the best place to get an isolator and how does it work?

Look at this link http://www.motorcycletrailer.com/kriss/
What it does is run the lights off the battery and use the bikes light wiring just to signal the relays instead of adding the load of the lights directly to the bike wiring.
