Meet the Magene Radar Bike Tail Light L508 — a compact, intelligent rear taillight that does more than just illuminate. Built for real-world riding, it combines bright LED signaling with millimeter-wave radar to actively monitor traffic from behind, giving you timely alerts and a clear edge on busy roads, windy descents, or twisty backstreets.

Why L508 is not just a light — it’s your riding partner

• Radar-assisted safety: Equipped with millimeter-wave pulse signals and a 40° radar beam, it detects rear vehicles up to 140 meters away, even around bends, and delivers visual and audible warnings to keep you informed as traffic approaches.
• Comprehensive visibility: A 220° viewing angle ensures riders in your peripheral field and vehicles from behind get noticed. The system’s warnings and display cues contribute to safer, more confident rides in urban streets and remote routes alike.
• Smart, adaptive lighting: Five light modes — solid, flashing, pulse, peloton, and radar-only — let you tailor visibility and signaling to your riding context, from high-contrast city nights to fast group rides.
• Smart brake sensing: The L508 automatically interprets braking cues and adjusts your taillight’s behavior to communicate your deceleration intent to following riders and drivers, reducing rear-end surprises.
• Long-lasting battery with auto efficiency: Auto-sleep/auto-wake minimizes power use when parked or idle. Battery life stretches to about 8 hours in peloton mode, 12 hours in pulse mode, and up to 3 months in standby, so you can ride with less frequent recharging.
• Rugged and reliable: ABS construction with IPX7 waterproof rating means this taillight stands up to rain, splashes, and wet road spray, so you stay protected in all weather conditions.
• Pure convenience with flexible connectivity: Recharges via USB-C and pairs with Magene Utility APP for quick setup, diagnostics, and firmware updates. It also communicates with a wide range of bike computers and wearables for seamless data and control.

Smart compatibility and ecosystem

• App and devices: Magene Utility APP for on-device control; compatible with Magene C406 Pro, Garmin models (130, 130P, 520, 520P, 530, 820, 830, 1000, 1030, 1030P), Wahoo (Bolt, Roam), Byron (R750, S500) and popular Garmin watches (245, 645, 735, 745, 935, 945, D2, Fenix series) and more.
• Connectivity: Bluetooth and ANT+ wireless protocols enable reliable, low-latency communication with your bike computer or watch for synchronized alerts and data display.
• Mounting: Specifically designed for seatpost mounting, providing a compact profile that integrates with most road, gravel, or commuter setups.

Who is this for?

• Urban commuters who want proactive rear awareness as cars approach from behind in traffic or at junctions.
• Group riders and peloton enthusiasts who need clear, non-intrusive signaling and responsive brake alerts during fast-paced rides.
• Riders on mixed terrain (city streets, bike paths, light trails) who value a compact, weatherproof taillight that won’t weigh down the bike.

Practical tips to get the most from your L508

• Pair with the Magene Utility APP to fine-tune radar sensitivity, alert tones, and light mode preferences for your typical routes.
• Enable peloton mode on longer, slower rides for consistent visibility while you stay aware of riders around you.
• Keep the taillight charged with the Type-C port and let auto-sleep save power during long standby periods between rides.
