I did mine today too!
I rapped rope around the tire and zip tied lights to it.
We'll see how long it last I guess since zip ties are kinda brittle when cold
I had similar noise from the rear cargo area but mine was more like constant tacky noise.
Turns out it was the tail gate rubbing against the rubber of the rear window.
Thanks to @Arterius2, Teflone tape like in the picture solved the problem :)...
I don't know if anyone is still following the post but I came across this product...
