Description

The TraceR 4 DayBright runs for up to 40 hours on a single charge, which for most riders is weeks of commuting or several days of bikepacking between top-ups. It weighs 35 grams, produces up to 200 lumens in DayBright pulse, and gives you 270° of side visibility so you stand out at junctions as well as from directly behind. USB-C brings it back to full in 90 minutes. The CNC-machined aluminium body and IP67 rating handle whatever winter does to it.

lets talk tech

Battery Status

A single press of the power button while the light is off displays the battery level for five seconds, providing a quick and convenient way to stay informed and prepared for every ride. This battery status is also displayed when the light is turned off.

Size

Engineered with a sleek, adaptable form factor, it integrates effortlessly into any environment while providing exceptional performance on demand.

Side visibility

Our optically clear 270° Commute Lens enhances side illumination, ensuring you stand out from every angle on the road. Whether you’re navigating dark paths or city streets, this setup delivers maximum visibility, safety, and rider confidence.

Weatherproof

Class leading waterproof ratings mean you will never be let down in any situations, and you can always depend on your light

Weight

Delivers up to 40 hours of runtime from a product weighing only 38 grams with no compromise to strength or durability.

Engineering

Daybright Flash

Our bespoke DayBright pulse pattern is specifically designed for daylight use, making it more conspicuous than a standard pulse and visible over a kilometre away, even in the brightest conditions. With DayBright mode, you’ll be noticed. Be Seen, Be Safe.

USB-C Charging

Offers fast and convenient USB-C charging, allowing you to power up quickly and get back on the road without delays.

Frequently asked questions

Both share the same 35g CNC aluminium body, the same 200-lumen output, the same 40-hour runtime and the same IP67 rating.

The ReAKT version adds two automatic modes: ReAKT, which flares the light up under braking and in bright ambient light, and Peloton mode, which dims the output when it senses a rider following you.

The DayBright is the simpler and lower-priced of the two, and is the better buy if you mostly ride alone or commute.

Up to 40 hours in the 150-lumen pulse setting. For a typical half-hour commute each way that is more than a month of riding between charges.

On a bikepacking trip it means the rear light is not something you have to plan your power budget around, which matters when you are already rationing charge between a GPS, a phone and a front light.

It means the light is visible across a 270-degree arc rather than only from directly behind.

That matters at junctions, roundabouts and side roads, where traffic approaches from an angle and a narrow rear beam can leave you effectively invisible until a driver is already committed to their move.
