G2FS LITH Rechargeable Rear Rack Bike Tail Light — 150+ lm, 220° Wide-Angle, IPX6

G2FS LITH Rechargeable Rear Rack Bike Tail Light delivers a 150+ lumen, 220° wide-angle red beam for highly visible, rechargeable rear-bike illumination.

Built for riders who want a compact, powerful taillight that mounts on a rear rack, seatpost or pack, this light balances brightness, runtime and weather resistance. It uses modern high-lumen LEDs and a built-in 500mAh Li-ion battery with multiple modes so you can tune visibility and battery life for commutes, night rides or all-weather weekend trips.

How bright is this taillight and how far can it be seen?

The G2FS LITH produces over 150 lumens focused into a 220° wide-angle beam designed to be visible from a distance and from multiple approach angles. That broader spread improves detection by drivers and other riders compared with narrow-beam rear lights.

• 150+ lumen red LED array for strong rear visibility
• 220° wide-angle coverage to be seen from side approaches
• High Flash and steady modes for distance and attention-grabbing signaling

What are the battery life and charging details?

The light houses a 500mAh rechargeable Li-ion battery and includes a power indicator that flashes red when recharge is needed. Run times change by mode, allowing you to trade brightness for extended hours on longer outings.

• 500mAh built-in battery with USB recharge capability
• Mode runtimes: Half Light 13.5 hr, Full Light 6.5 hr, Breathing 13.5 hr, Slow Flash 25 hr, High Flash 14 hr
• Power indicator shows low battery with a red flash

Is the light durable and easy to mount?

The unit weighs just 2.29 oz and is IPX6 waterproof, making it resistant to heavy splashes and rain during everyday riding. Its simple mounting system slips into seconds on racks, seatposts or bag straps and the compact body fits into a pocket for off-bike use.

• IPX6 rating for rain and splash protection
• Ultra-light 2.29 oz construction for minimal added weight
• Quick-install clamp fits racks, seatposts and packs — no tools required

Which light modes are available and how do they operate?

Five selectable modes let you prioritize steady visibility or battery-saving flashing patterns depending on conditions. The control is a single button: press to cycle modes, double-click for High Flash, and long-press to turn off while retaining the last mode used.

• Five modes: Half Light, Full Light, Breathing Flash, Slow Flash, High Flash
• Long-press turns light off; next power-on remembers last mode
• Double-click from any mode to instantly enter High Flash

Who this is for: Riders who commute after dark, cycle on mixed roads, or take multi-day trips will benefit from the G2FS LITH’s combination of wide-angle visibility, selectable runtimes and weather resistance. It’s also suitable for hikers, campers or boaters who need a compact rechargeable red light that installs quickly and performs reliably in poor weather.
