Exposure Sirius MK7 & Tracer MK2 Reakt Light Set

The Sirius + TraceR ReAKT Pack is the premium package with high power in a compact front light that is as at home in either a road race or lighting the urban commute and can be adapted easily with a choice of 7 programs as well as USB convenience as well as Smart Port+, allowing the addition of optional accessories including Support Cells and remote switch.

Combined with intelligent and extremely lightweight rear lighting that features:

  • Ambient Kinetic Technology (ReAKT) enables the light to automatically flare under braking and when entering areas of higher ambient light to create a contrast in brightness.
  • Peloton mode utilises ReAKT Technology for use in a chain gang by dimming upon detection of a rider’s front light, preventing a dazzling effect, but flaring up as a beacon at the tail of the pack.
  • Both lights feature USB convenience, a choice of 6 burn times per light, DayBright flash pattern and side illumination for 360° visibility.
