If you want to be safe while you’re riding, you need lights on your bike. There are some fundamental problems with most lights that never really got addressed with most design revisions. You have to take them off your bike, or they might get stolen. If you do that, then you have to carry around bike lights. They’re also generally too bright and could potentially induce epileptic seizures in those drivers and cyclists you’re trying to make aware of your position. Most of them are also ugly. None of these things are an issue with these new Double O bike lights. Once you attach the mounts to the bike itself, the front and back Double O lights attach to the bike (and each other) with neodymium magnets. Because of the hole in the middle, the lights can be secured with the same lock you use for your bike. On the actual illumination side, Double O uses a higher number of properly spaced, less bright LEDs to counteract causing blindness.
