Product Information

Full details

The Exposure Lights Trace + TraceR 4 ReAKT Light Set is designed for road cyclists and commuters who demand high-visibility safety in a lightweight, aerodynamic package. The primary benefit of this system is its intelligent ReAKT technology, which dynamically adjusts brightness based on braking and ambient light levels, ensuring you remain visible without constant manual adjustments. While the set offers industry-leading performance and durability, users should be aware that the compact form factor limits the maximum burn time compared to larger, heavier endurance-focused lighting systems.

FAQs

Can I use these lights for mountain biking?

While they are rugged, the 360-lumen output is optimized for road visibility rather than trail illumination; a dedicated higher-lumen off-road light is recommended for trails.

How do I know when the light is fully charged?

The integrated LED indicator will change color or stop blinking once the unit has reached 100% capacity.

Is the mount universal?

The lights use standard Exposure mounts that are compatible with most seatposts and handlebars, though aerodynamic seatposts may require specific adapter straps.

What is the maximum runtime?

The lights can run for up to 40 hours depending on the mode selected and the intensity of the ambient light surroundings.

Are the units waterproof?

Yes, they feature an IP67 rating, meaning they are protected against dust and can withstand temporary immersion in water.

Troubleshooting

Light does not turn on after charging

Ensure the USB-C cable is fully seated and the charging port is free of debris; try a different power brick to verify the power source.

ReAKT technology seems unresponsive

Clean the rear sensor window to ensure it is not blocked by mud or grease, which can interfere with ambient light detection.

Pros and Cons

Pros

  • Extremely lightweight at only 35g per unit
  • Smart ReAKT sensors reduce the need for manual mode changes
  • Durable aluminium construction survives rough usage
  • Rapid 90-minute full recharge time
  • Excellent visibility through DayBright pulse patterns

Cons

  • Smaller battery capacity compared to larger lights
  • Not intended for technical night mountain biking
  • Advanced features require periodic sensor calibration checking

Setup, Compatibility & Care

Mounting these lights is straightforward due to their compact design and secure strap mounts, which fit a variety of handlebar and seatpost diameters.

Setup Steps:

  1. Secure the mount to the desired position on the bike frame or handlebar.
  2. Click the light into the mount until it snaps securely.
  3. Adjust the angle to ensure the front light is pointed slightly downward to avoid blinding oncoming traffic.

Care Instructions:

  • Always ensure the USB-C port cover is fully closed after charging to maintain the IP67 seal.
  • Periodically wipe the lenses with a damp microfiber cloth to remove road grime that can diffuse light output.
  • Avoid using harsh chemical cleaners, as these can degrade the aluminium finish over time.
