The Trace 4 delivers a scarcely believable 360 lumens from a 35g package, which makes it the easiest light in your life to actually remember. It lives in a jersey pocket, a rucksack lid, a saddlebag or clipped to the bars all week. USB-C charges it fully in 90 minutes. A tough CNC-machined aluminium body and an IP67 rating mean British winters are not its problem. Whether you commute through traffic or head out on faster roads at the weekend, the Trace 4 punches well above its weight.

Most rear bike lights do one thing at one brightness and hope for the best. The 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 35g 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.
