Planet Bike Superflash USB-Rechargeable Tail Light: Red/Black

The Planet Bike Superflash USB-Rechargeable Tail Light (Red/Black) is a compact, ultra-reliable rear bike light famous for its eye-catching Superflash™ mode that maximizes visibility in traffic—ideal for commuting, road riding, night rides, or any low-light urban or rural scenarios.

This model features a high-output surface-mounted LED plus 2 additional 5mm LEDs, delivering modes including Steady (~4 lumens), Courtesy™ (variable low output), Pulse, and the signature Superflash for aggressive flashing attention. It provides 180°+ visibility (with strong side lighting) and is daylight-visible in many conditions. The built-in 270mAh lithium-polymer battery recharges via USB (often micro-USB or USB-C depending on batch; cable included) in 2-4 hours, offering up to 36 hours runtime on Superflash or longer in lower modes. The ultra-compact, weatherproof (IPX6-rated) housing is lightweight, durable, with a soft-touch power button, low-battery indicator (flashing pattern for last ~20 minutes), and a versatile quick-release strap/clip mount for easy attachment to seatposts, bags, or helmets.
