Product Details

Exposure Tracer MK2 - 75 Lumen Rear Light

Intelligent and extremely lightweight rear lighting for commuting, road cycling and Time Trial. 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.

Updated with 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. Features USB convenience, a choice of 6 burn times, DayBright flash pattern and side illumination for 180° visibility.

In the box:

  • TraceR MK3 ReAKT Peloton
  • Seatpost bracket
  • Smart charger
  • USB charge cable
  • Quick start guide


ReAKT (Ambient Kinetic Technology) is at the next generation of rear lighting, a light that adapts to the conditions of the ride. By flaring up under braking forces or automatically adjusting to the surrounding ambient light ReAKT Technology makes your rear light a beacon for safety.


The Optimised Mode Selector allows you to easily select from a concise number of programs to provide the optimum lighting for your ride.


Controlling the temperature of the LEDs is important in ensuring that the lights remain as efficient as possible. Patented technology in the circuitry of Exposure Lights stop the light from heating up to a point where the light loses power due to the elevated temperature. Patent Applied For.
