Exposure Lights BOOST-R 3 REAKT Rear Light

Engineered by Exposure Lights, the BOOST-R 3 REAKT Rear Light is the ultimate “be-seen” rear light for everyday commuting and training rides. Its compact, feather-light construction keeps your bike setup clean and unobtrusive, making it ideal for city riders who value performance without bulk. Whether you’re commuting daily or riding year-round, this rear light delivers premium visibility without compromise.

ReAKT Technology

What truly sets the BOOST-R 3 REAKT apart is its intelligent ReAKT technology. The light automatically adapts to ambient light conditions, increasing brightness in well-lit urban environments and reducing output in darker areas to maintain maximum contrast. This ensures you’re always clearly visible, without dazzling other road users. Add in ReAKT braking, which flares instantly when you slow down, and you have rear lighting that actively communicates your movements—boosting safety in busy traffic and on fast country lanes alike.

Adaptive Lighting

For group rides and social cycling, the PELOTON mode is a game-changer. The BOOST-R 3 detects the front light of a rider behind you and automatically dims to prevent glare, then returns to full brightness when they drop back. Combined with the powerful DayBright pulse pattern, visible over a kilometre away even in bright daylight, you’re impossible to miss while still being considerate to others on the road.
