Exposure TraceR 4 ReAKT Rear Light
Most rear bike lights do one thing at one brightness and hope for the best. The Exposure TraceR 4 ReAKT pays attention. It flares up when you brake and when the light around you gets brighter, then eases off for the rider sitting on your wheel. All of that comes from a 38g package delivering up to 200 lumens, charged over USB-C in 90 minutes.
A CNC-machined aluminium body and IP67 rating mean it shrugs off a British winter. Pair it with the Trace 4 front light and you are properly visible, day or night, at either end of the bike.
Key Features
- ReAKT reactive light technology: automatically increases output when you brake and when the ambient light around you gets brighter, with nothing to press while you ride
- Peloton mode: senses the light of a rider following you and automatically reduces output to avoid dazzling them, built for club runs, chaingangs and group riding
- ReAKT and Peloton do not run at the same time, and you can switch either on or off
- DayBright pulse pattern: designed for daylight use, more conspicuous than a standard pulse and visible over a kilometre away
- Up to 200 lumens in DayBright pulse, and 75 lumens constant for lit roads after dark
- 270° Commute Lens: optically clear, for enhanced side illumination
- Battery status: a single press of the power button while the light is off shows the battery level for five seconds
- Up to 40 hours of runtime
- USB-C charging in 90 minutes
- CNC-machined 6063 aerospace-grade aluminium body with a scratch resistant polycarbonate front lens
- IP67 rated
- Weighs just 38g
- Designed and built in the UK

Why Choose the Exposure TraceR 4 ReAKT?
A rear light’s job is being seen, not seeing. The TraceR 4 ReAKT responds to braking and to the light around you, so it stands out in bright sun and low winter glare, and eases off when you’re riding in a group. It does this in a compact 38g package that charges over USB-C.
