Turn signals

Installed new LED light bulbs equivalent to the stock 3157 bulbs to replace the old style 3157 incandescent bulbs. I also replaced the 5 pin TS relay with one that was described to work for my truck with LEDs. Everything seemed to work fine, I checked the lights in the run position, both TS, and 4 way flashers. It all worked, turned on the truck to charge the battery (while leaving the lights on because it was dark) while I cleaned up and put away my tools. I noticed I left my passenger side blinker on, went to go turn it off and it stopped by itself. Tried to turn on either blinker and 4 way flashers. None worked. Parking lights still work (parking and turn signal lights work off same bulb and wiring in this model). I changed back to the old relay, thinking I got a bad "new" relay and that I would get "hyper flash" but still nothing. Short of chasing wires all the back to the cab harness, I have checked all wiring. No wires are frayed, cut, exposed, etc. It seems weird that it would work perfect then stop all the sudden. Especially when both relays won't work (no audible click at all). Any help or suggestions would be greatly appreciated. Thank you and have a good day/evening.
Do you

Yep, We have seem this problem before, what happens is the LED light kit amplifiers (in the bulbs) are cheap and they can stop working and cause the lighting system to have problems. Try removing he bulbs and replacing them with the originals.

Please let us know what happens.
