The Exposure Lights Sirius Mk3 front light is billed as a light for urban riding and commuting and so was tested on an hour-long commute home, starting in the half-light and ending in pitch dark.

It couldn’t be easier to use — double press the one operating button on the rear (which also acts as a battery health indicator), or continue holding for flashing. The flashing ‘SOS’ mode gave much needed security against the usual hazards when riding through town.
