Hi everyone. One side of my thin lines has gone out. It is not responsive to a power source but the other side is perfectly fine. any ideas?

switch ballasts from left and right.

check signal fuses, if spliced power from signals.

thanks. checked them. one side still out

did you swap the ballasts from what side to the other? or if you already have you're halo rings soldered to your corners it might be easier just to take the headlight that the halo rings aren't working in, out and hold it over to the other side and use that ballast to see if it's teh ballast or the rings that are bad. did you check your power and ground connection for the ballast to make sure its still a good connection?
