The popular and super flat LED rear light TOPLIGHT Flat now also features the new LineTec technology: In the TOPLIGHT Flat S, the light from one high performance LED is spread out by the patented lens system into a brilliant strip of red light. If a car approaches from behind, this strip makes it easier for the car driver to estimate the distance to the bicycle - a vast safety improvement. The rear light also shines laterally in a large beam angle of 320° - best visibility. Available as a dynamo powered rear light with electronic standlight function or as a battery version with optional automatic activation (senso). Integral large reflectors.
