Exposure Lights Tracer 4 ReAKT Rear Light

The Exposure Lights Tracer 4 ReAKT Rear Light is a compact rear bike light built to improve visibility in changing road conditions. Its ReAKT technology raises the light output when you brake and when the surrounding light gets brighter. This helps you stand out without needing to change settings as you ride. It delivers up to 200 lumens, weighs just 35g and has a tough IP67-rated aluminium body.Key Features and Benefits:ReAKT Reactive Technology: ReAKT responds to both braking and changes in ambient light. The light increases its output when you slow down, which gives road users behind a clear signal. It also boosts output when the surrounding light gets brighter. This helps the light stay visible in bright sun and low winter glare.Peloton Mode: Peloton mode senses light from a rider behind and lowers the output of the rear light. This reduces glare for anyone riding close to your wheel. It makes the light better suited to club rides and group riding, where full output is not always needed. ReAKT and Peloton modes can be switched on or off to suit each ride.Up to 200 Lumens: The light can produce 200 lumens in its DayBright pulse setting. This high output helps it stand out during daylight rides. A 75-lumen constant setting is also available for use on lit roads after dark, giving you an output suited to different riding conditions.Up to 40-Hour Runtime: The battery provides a maximum runtime of 40 hours. This cuts down on how often the light needs charging and makes it practical for regular commuting, training and longer rides.USB-C Charging: The built-in battery charges through USB-C and takes around 90 minutes for a full charge. USB-C makes it easy to use a common charging cable at home or while travelling. The short charge time also helps get the light ready for your next ride.35g CNC-Machined Aluminium Body with IP67 Protection: The CNC-machined aluminium body keeps the light strong while holding its weight to just 35g. Its IP67 rating protects it from dust and water, so it can cope with wet and dirty riding conditions through the year.The Tracer 4 ReAKT is designed to help other road users notice both your position and changes in your speed. ReAKT handles changes in output for you, while Peloton mode gives you more control during group rides. This makes the light useful across commuting, road training and club riding, without adding much weight to the bike.With reactive lighting, strong daytime output and a compact weather-resistant build, the Exposure Lights Tracer 4 ReAKT Rear Light is a practical choice for regular road use. A seatpost bracket and USB-C charging cable are included, so it has the core parts needed for fitting and charging.In the box: TraceR 4 Reakt , Seatpost Bracket, USB - C Charge Cable.
