Description

The Exposure Lights TraceR Mk3 DayBright is a rear bike light that puts out up to 75 lumens from a single red LED, in an anodised aluminium body that weighs 35 g. It has a DayBright pulse for daylight riding, charges by USB-C, is rated IP65 and comes with a seatpost mount.

Who it's for

Road riders and commuters who want a rear light small enough to forget about and bright enough to be seen in full sun. At 35 g and 57 mm long it suits a race bike as well as a commuter, and the DayBright pulse earns its place on a bright morning bunch ride along the coast or a run through city traffic.

Brightness and runtime together

Three programs set how bright the TraceR Mk3 runs and how long it lasts. Each has a constant mode and a pulse mode:

High (program 1) - 3 hours constant, 6 hours pulse
Medium (program 2) - 6 hours constant, 12 hours pulse
Low (program 3) - 12 hours constant, 24 hours pulse

Double the runtime and you halve the output, so High carries the full 75 lumens. DayBright is the pulse mode in program 1: a pulse pattern built for daylight, visible from over a kilometre away, that runs for 6 hours. That covers a long weekend ride or a week of short commutes on one charge.

Beam shape

The lens throws light to the sides as well as straight back, so drivers pick you up at roundabouts and side streets, not only from behind. The seatpost bracket is angled so the light points directly back down the road when it is fitted.

Charging and battery

The 850 mAh lithium-ion battery recharges through a USB-C port in 1.5 hours, and a USB-C charge cable is in the box. A Fuel Gauge shows the charge left each time you switch off: green for 100 to 50 per cent, amber for 50 to 25, red for 25 to 5, and flashing red below that.

Mounting

The seatpost mount fastens with a silicone band, no tools needed, and the light clicks into it. Swapping the TraceR Mk3 between bikes takes seconds.

Weather resistance

The TraceR Mk3 is rated IP65, in a body machined from anodised 6063 aluminium. Seat the silicone band back over the charge port after charging to keep water out.

Looking after it

Wipe mud off the lens gently and keep high-pressure hoses away from the light. If it sits unused, recharge it once a month to look after the battery.
