Heres some science:-

How do you know you need one of these? When you remove your saddle and your seatpost looks like the one in the 2nd picture to the right then you need one of these!
You might have a light on the front and the back of your (long)bike but what about the sides. The flashing LEDs in these pedals make you visible from both sides so other road users waiting at junctions (for example) have a greater chance of seeing you and thus less chance of pulling out into your path!
The added bonus is you'll never have to put batteries in either (they work by the motion you create whilst pedalling) - so they are 'green', low maintenence, increase your road safety and thus, we think - Practical! They even carry on flashing for upto 5 minutes after you stop pedalling. Metal studs make these pedals good in the wet and dry!
