Color-Changing Tire Valve Lights

I like the light display, I didn’t like the fine thread I couldn’t tell or get the battery compartment to catch on the thread to screw it on securely it would pop open on its own i think the thread is stripped while i was trying to screw it on the battery compartment also one of the battery was covered with a green waxy build up i cleaned it off with my knife edge and so I tested all the batteries they register good but I can’t get between the battery side and the light side to screw on and stay with out it popping open. The thread in that area are to delicate and subjected to stripping. I think you need to work on that thank you for the experience working with that.
