The Serfas Pluto is the brightest battery tail light we have ever sold under $25.
The Micro LED Strip outputs 25 Lumens on high, 4x as bright as the standard diode type LEDs used in other affordable tail lights.
It runs on a single pair of AAA batteries (included) and has both solid (40 hour run time) and flashing modes (150 hour run time).
Includes a seatpost mounting bracket and also fits Serfas' rear rack mounting bracket.
Backed by Serfas' Lifetime Warranty.
