ICON is primarily designed as a 'to be seen' light, giving up to 270 degrees of side visibility. This is ideal in urban environments. If you are riding on unlit roads, we would recommend pairing ICON with a 'to see' light.
As ICON has twin LED's (one with a focused output, and the other with a dispersed output) the ICON front can be used as a back-up to your 'to see' light. It will get you home on a dark unlit road, but is not specifically designed for this purpose.
