I bought a FleX Swirl Finder Light it came with batteries(aaa) I took out the batteries open the light notice that there is 2 contacts(+&-) and 3 batteries knowing it wouldn't work insisted to place the batteries in the light tightened the cap, but I noticed the batteries were shaking in the light which means it wasn't making contact so can someone tell me if my light is defective (that's what I think) or am I doing it wrong
