Premium Vehicle Wheel Nut Protective Decoration Caps with Motion Activated White Light (4-Pack)

Pros: Looks as native part of the car - like a "secret" nut of the wheel. Doesn't go out of the wheel, so one can't break it down on a carb or somewhere in a mud. Doesn't light in a day-time but attract attention of others when it becomes dark. Sits solidly on a wheel nut, no chance just to loose it. Good outside quality and look.

Cons: Internal construction is a shame on engineers. Two thin supply elements lay on each other without side isolation. The top one easy makes shortcut curcuit with metallic "bridge" - positive contact and becomes empty very fast. I've ordered that twice - one piece first time and 2 pcs second time. First time 1 of 4 didn't work, second time none of 8 didn't work - all because of discharged top battery.

Other: Funny thing for tunning but only for those who know how to use screw driver and soldier and has some basic knowledge in electricity.
