Night Golf Ball LED has a built-in timer, which after a stroke, activates and lights up the two built-in LED's for about 8 minutes. Every time the ball is hit, the timer resets and the 8 minutes start over again.
This allows the ball to be lit all the time. It's a very nice ball to play with. The built-in batteries have a minimum running time of 10 to 15 hours and have a lifetime of about one year.
with built-in timer (about 8 minutes)
with 2 LEDs
Available in green, blue, white and red
Note! This ball does not blink, but shows a steady light and is not to be confused with a blinking ball without reset function. Without the reset function you have to wait until the lights go out before you hit it again.
