LED Headlights, the cheap ones.
Headlights Do Not work with the switch, only the Park Lights. This video shows how to "Fix" this problem by unplugging the Headlamp Delay Relay which Did Not work. The lights will work with this plugged up but it Buzzes and clicks of. Is the any other way of bypassing this with the stock wiring? Maybe adding two separate relays for each setting (Low/High)? I tried it myself by jumping a couple of the wires but I was blowing fuses...

 

UPDATE:
I installed a Stock set of Headlights and they will not come on with the Headlamp Relay hooked up but the LED's will?? Any thoughts?

 

If it worked ok before, you have probably disturbed a poor connection

As I always say..circuit diagram and test light

 

Well, they were on a toggle switch when I got the Jeep, I just recently started to try to get them to work on the original switch. Not sure why they will not work from the switch even with the relay unplugged because there is nothing on it that has anything to do with the lights other than a lights on signal

 

Have you tested the headlight switch? it might just have a bad "headlight" output.

 

Would that cause the Headlamp relay under the dash to open and close fast til it stops working?
