The Exposure Lights TraceR 4 Rear Light is a compact, high-output rear light built for daily road use, commuting and longer rides. Its standout 40-hour maximum runtime cuts down on charging, while DayBright pulse delivers up to 200 lumens to help you stand out. A wide 270° beam adds side visibility at junctions and roundabouts. The light also weighs just 35g and uses a tough, weather-resistant aluminium body.Key Features and Benefits:Up to 40-hour runtime: The battery can run for up to 40 hours in its 150-lumen pulse setting. This means less frequent charging for regular commuters and more usable ride time on long trips.200-lumen DayBright output: DayBright pulse reaches up to 200 lumens to create a strong rear signal during daylight. This helps make your position clearer to other road users when ambient light is high.270° side visibility: The beam can be seen across a wide 270° arc instead of only from directly behind. This improves visibility to traffic approaching from the side at junctions, side roads and roundabouts.USB-C charging: The internal battery charges through a USB-C connection and can return to full charge in around 90 minutes. This makes it simple to top up with a widely used charging cable between rides.CNC-machined aluminium body: The light uses a machined aluminium housing rather than a basic plastic shell. This gives the unit a strong outer body while keeping total weight down to just 35g.IP67 weather protection: The IP67-rated construction is made to cope with wet and dirty riding conditions. This gives you a rear light suited to year-round commuting and winter road use.The TraceR 4 is designed to give you dependable rear visibility without adding bulk or constant charging to your routine. Its long battery life suits frequent rides, while the 270° beam helps cover the angles where a standard rear-facing light can be less effective. The supplied seatpost bracket gives you a secure mounting point, and the USB-C cable is included for charging.For riders who want a small rear light with strong daytime output, broad visibility and long battery life, the Exposure Lights TraceR 4 is a practical choice. Its low 35g weight and durable build also make it easy to leave fitted for everyday use.In the box: TraceR 4, Seatpost Bracket, USB - C Charge Cable.
