Doesn't fit presta valves,
Verified Purchase(What is this?)
This review is from: HOTER Bike LED Flash Light Wheel Valve Cap Bicycle Lamp(Price/Piece) (Misc.)
Turned up quickly and is a clever gadget (very bright). However despite what one of the other reviews said these will not fit a presta valve (this is the common sort for a road bike which is thin with a small knob that you tighten to stop the valve opening). It looks like it might but there is not enough of a hole in the base to go over the knob. It comes with a fitting for a Schrader valve which is the type you get on a car and on a lot of mountain bikes so have fitted them to my wife's bike instead.
