The Topeak HeadLux Dual Head and Tail Light simplifies your safety system. This light features a white light to the front and red to the back, so when mounted on your helmet or drop tube (straps included) it eliminates the need for multiple lights. Up to 140 and 40 lumens of white and red light make your position clear to other road users, and multiple modes allow you to adjust for changing conditions as the sun rises or sets. The LED bulbs are battery-efficient, and the HeadLux comes with a charger so you can easily recharge and get back to riding.
