The Twilight Tracer golf ball. £12.99 ($20.65). There’s a joke in here somewhere involving flashing golf balls and midnight games, but darned if we can find it.

 The official size and weight of the U.S.G.A and R&A, the Flashing Golf Ball has a tough Surlyn cover and a super-bright internal LED that flashes for five minutes after contact. It has a battery life of 80 hours, which will keep you flashing (as it were) for about 1000 strokes! The ball also comes with two tees and a carrying pouch for the ball – so you can whip out your special ball whenever it looks like the hole demands it (which is every hole for us lot).
