The Busch & Muller Lumotec Classic T Senso Plus Dynamo light is styled much like the cool vintage bicycle lights of the 1950s. But the internals are all modern, using three powerful LED bulbs and a focused optical system giving you a capable 30 LUX of power, Senso technology (light automatically turns on when its dark) and "stand light" technology, which basically means it keeps shining even when you stop. Ideal for traffic lights.
A top mounted switch allows you to change from three different settings: "T" This the daytime running light mode which gives the best visibility during the day or foggy weather. "S" Switches automatically from daylight running mode to Nighttime running mode which is slightly dimmer as to not blind oncoming traffic. "0" Turns the system off (after the stand light has diminished).
Supplied with a Stainless Steel fork crown mount that's suitable for caliper, roller, disc or V brakes, a 60cm cable with two 2.8mm female spade connections for connecting the light to your front dynamo hub.
