Problems keeping TPS sensors on the bands for aftermarket wheels.

Before I dealt with a light, I'd try something like this.

They make TPMS in all sorts of designs, even regular rubber pull through designs. That's what I'm using on my Winter wheels. Not sure what you're dealing with on your wheels that made you go with bands, but not many OEMs other than a few Fords used them that I know of. You may be figuring out why its not a common solution.
