When one of my Wildcat's taillights became "non-functioning", I found a blown fuse in a fuse block under the hood of my GMC tow vehicle. My taillights are individually fused.
I agree with Lincman983. Call the factory, they have sent me the parts I needed, be ready to provide them your last 6 digits of your trailer's VIN.
Good Luck.

I my called my dealer and he contacted Cedar Creek for a LED taillight on our 2016 CC which had one LED fail inside of the unit. I got tired of waiting and went on E-trailer.com and ordered a LED taillight, that would fit. This is the LED taillight I ordered, and it worked fine for me. I believe it was $20+tax and shipping.
