I find that I can see cyclists better if they have a flashing white light.... In the city at least, with all of the other lights around, a flashing white front light identifies you immediately as a bicycle. A steady headlight can look like other things... I prefer to use a steady headlight to see with and a flashing one for safety myself. Of course all lights should be positioned so that they are not directly in the eyes of other people. My steady headlamp is aimed at the ground and my flasher is more straight on - but it is not a super bright HID light...
