Riding at night can be fun, it can also be extremely dangerous if you cannot see the terrain in front of you. Explore more with the QuietKat Explorer 2000 Light. This advanced bicycle light features two 600 lumen white lamps, two 300 lumen red lamps, brightness selection, and a strobe function. Use the white light for maximum visibility. Use the red light to avoid disturbing wildlife, since most animals cannot see red light. The light can be mounted on the seat-tube or pannier rack. It can be placed in RED mode to be used as a taillight. The USB output port allows users to charge a phone, GPS, or other electronic devices that use a 5V USB plug.
