Lezyne Radar Drive 300 Taillight

The Lezyne Radar Drive 300 Taillight is a rear safety light designed to improve rider visibility in traffic, low-light conditions, and night rides. Using a high-efficiency LED paired with optimized lens optics, it produces a broad, even beam pattern that enhances rearward visibility to drivers and other trail users. The light’s output blends brightness and wide coverage to help make the rider noticeable from longer distances without harsh glare.

Radar Drive 300 offers multiple output modes including steady, pulse, and flash settings. Each mode is tuned to balance brightness and battery life for different riding environments: steady modes for consistent visibility and flashing modes for higher perceived visibility in urban traffic or group rides. The unit is USB-rechargeable, powered by a built-in lithium-ion battery with an integrated charge indicator to show remaining battery level.

The mounting system uses a flexible strap that fits a wide range of seatpost diameters and shapes, making installation and removal tool-free and quick. The taillight’s durable construction and weather resistance make it suitable for everyday commuting, dawn/dusk workouts, and all-night adventures.
