It happened to me. It's a fuse. I'll try to take a pic of it later tonight or tomorrow.
It's definately not a fuse, it's a bad ground. That's why it makes that clicking noise when the lights come on, and the backlights go off.
I'll post a link on how to fix it...https://www.celicahobby.com/ubbthrea...#Post1869995853
Just do what it says, and have fun.
This is a common problem in our cars. Not sure why it happens, but at least the fix is easy. Just cut some of the plastic wire covering away, and route a wire from an existing ground to the wire that it says to do it to in the post above. Doing so will ground the wire again and fix your problem. You don't have to use a tapping clip, but you can if you want. You can always use electrical tape.
