If you’ve ever had difficulty finding your balls after dark (golf balls that is) then these might just be the answer, the Twilight Tracer Golf Balls.
The twilight tracer golf balls have all the required functionality of a conventional ball (feel, accuracy, distance, regulation size and weight, etc.) and look exactly like a normal ball. That is until you hit it, where upon it changes from a boring white dimpled ball to an all singing red flashing flying sphere. The flashing effect lasts for 5 minutes, so that you can still find the ball after a leisurely stroll.
You can get the twilight tracer golf balls from latestbuy for $39.95 (AUD).
