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.

Once on a darkening country lane you can select a ‘low’ constant beam by simply ‘scrolling’ through the three beam settings (high/medium/low) using the one button.

The mount, affixed with a rubber strap, enabled me to position the beam by tilting the light forward/back; the rubber mount though does mean the light does ride up occasionally, especially when it’s bumpy — Exposure makes a more stable fixed mount which the Sirius will click in and out of.
