Fixed-gear bikes are a testament to minimalist styling, however most light mounting hardware isn't. The BikeLit aims to rectify the situation by simply hanging on.
The BikeLit by Nite Ize uses two LED beacons - one white, forward-facing that clips to the front brake cables and one red, rear-facing that hooks to the saddle rails. By putting the lights out at the very edges of the bike, you're more easily delineated than if you were, say, wearing a helmet light and rear flasher in your belt loop. The two-colour system also helps oncoming traffic orient which way you're travelling faster and more instinctively. And the complete lack of mounting hardware means you can you can be seen without cluttering your handle bars.
