Made by Los Angeles-based bike light manufacturer Lumenus (which previously brought us a cycling jacket with integrated turn-signal lights), the complete ioLight system consists of a free iOS/Android app, plus a Bluetooth-equipped white LED headlight and red tail light – that said, the color of the LEDs can be changed via the app.

Before setting out on a ride, the user starts by opening the app and indicating their destination. The software proceeds to select the quickest cycling-friendly route from their present location to that place.

Once they start pedalling, the app automatically alerts them to upcoming turns by sequentially flashing the headlight’s strip of LEDs in the direction of the turn. The tail light likewise flashes in that same direction, with both lights letting motorists know which way the cyclist is heading.
