Description



The GUEE Theta-K is a great headlight for anyone planning to ride in the dark. Night riding cyclists need both focused light so they can clearly see and avoid obstacles in their way as well as a wide field of illumination so that they too, can be seen. The GUEE Theta-K provides a solution for bicycle riders which achieves both optimal brightness and light distribution with a super-bright CREE LED - and it has been approved by the German StVZO. StVZO is a German acronym (Straßenverkehrs-Zulassungs-Ordnung) and roughly translates to road traffic licensing authority. Lights are required to have a minimum brightness, a beam pattern with a horizontal cut-off, and the brightness must be below a certain value for a certain height to protect oncoming traffic from being dazzled. The beam of our GUEE Theta-K is focused from the front wheel out to 10 meters in front of the bicycle, as well as being distributed in a wider arc in front of the wheel, illuminating the rider's path. 

The built-in smart auto sensor (SAS) automatically controls the brightness depending on the light conditions of your surroundings. The built-in rechargeable battery is easy to charge via USB and has a 4-level battery indicator so you know how much power you've got left. The tool-free, quick-release buckle of the GUEE Theta-K allows you to take off the front bike light whenever you have to leave your ride. For rainy weather, the GUEE Theta-K is IPX5 approved, which means you can ride even with water jets coming from any direction.
