When the DeLorean vanishes in Back to the Future, it leaves two burning tyre tracks on the asphalt. Your ride home from games night deserves a bit of that drama too, just without the flux capacitor and without a visit from the fire brigade afterwards.
That's what the LED Valve Lights for Your Bike are for. Screw one onto the valve of your front wheel and one onto the back wheel, that's all there is to it, no tools needed. As soon as you start pedalling, the coloured LEDs blur into a bright ring that turns with the wheel. There are seven flashing modes to choose from, from calm steady light to frantic colour changes, and the button cells are already included.
Please check your valve first: The lights fit car-type valves (Schrader) and Dunlop valves, as found on many everyday, kids' and mountain bikes. They do not fit French valves (Presta or Sclaverand), the slim valve with the small knurled nut at the tip.
For everyone who rides in the evening and would rather stand out than be overlooked. You'll still have to organise the time travel yourself.
