Thanks for the help. I’m really a noob but first thing I’m going to try is test the fuses. The wiring and stuff is to complicated for me.LED's usually will not go bad on both sides at the same time.
Check to see if you have voltage to the brake/tail light assembly.
If not, a wiring diagram will help to back track the circuit to see where you are losing power.
If you do have voltage to the tail light assembly, check your connections, and use a fused jumper to test to see which LED's will turn on.
Last step willbe to check your grounds.
