I was looking for a light that has both bright and a long "term". After I receive the kit, I set equal to the assembly. The attachment of the two lights was very simple .... looking right position, fasten with the corresponding O-ring and that's it. Now even the lamp charge (with a standard USB cable) and everything is ready. A bit of tact I brazcht only when inserting the batteries into the tail light. This is a bit difficult to open. The following weekend I was able to test it right. During an approximately 7-hour drive of the Speedster persevered without problems. It was indeed informed me while driving through a red flashing LED that the battery is empty slowly, but after I reduced the brightness, the battery lasted almost one hour. Thanks to the USB cable I could charge the battery even during the return trip in the car. Since the price / performance ratio fits, warcdies a worthwhile purchase for me.
