Exposure BoostR DayBright ReAKT Tail Light

BoostR DayBright ReAKT Tail Light—adaptive visibility, brake-reactive lighting, and daytime pulse

What Our Gearhead® Experts Are Saying:

"I rely on the BoostR DayBright ReAKT Tail Light for high-visibility safety, day or night. The brake-reactive feature is excellent in traffic, and the Peloton mode keeps it from blinding other riders. The DayBright pulse pattern is super visible—even in direct sunlight, so I know I’m always seen."

For a tail light that adapts to your environment and enhances your safety, the BoostR DayBright ReAKT Tail Light from Exposure is the way to go. Its advanced DayBright pulse pattern cuts through even the sunniest conditions, making sure we’re visible from over a kilometer away. When night falls, the REAKT technology automatically adjusts brightness based on ambient light and braking, delivering maximum contrast where it’s needed most. In Peloton mode, the light dims when it detects a rider directly behind, making it ideal for group rides. The ITM circuitry monitors LED temperature, reducing power when needed to maintain efficiency. Compact yet robust, the BoostR DayBright ReAKT keeps us safe on every ride.
