Busch & Müller Toplight Line Brake Plus Brake Tec Pulsating (50mm only rack mount) taillight rearWires to a compatible 3W dynamo headlight/hub. The wire to power it from the headlight is not included.This is maybe the best DYNO powered rack mount tail light you can buy right now. Instead of an LED blasting straight ahead, it's reflected and focused in a precise way that makes it a flat beam.You're not a speck of red light but a fat bright line, which helps depth perception for drivers. You have to see it in the dark to really get it. Only the top portion of the light contains the LEDs, the bottom 3/4 of it is a big sophisticated reflector. Peter White regarding the Brake Tec "pulse" function: "The Toplight Line Brake Plus senses when the bike slows under braking and glows brighter. It does this by monitoring the AC frequency from the hub. During braking, the AC frequency slows quickly, and then makes the LEDs pulse or flicker, hopefully getting the attention of that fool in the jacked up SUV behind you." Fun fact: In Germany B&M has dominated the rack mounted tail light market for so long that their name "TopLight" is synonymous with rack mounted tail lights in general, from any brand. A synecdoche!Comes with no wires. B&M323ALTV-A Important: You need this adapter to make these work on older single-hole Nitto rear racks. These lights have two bolts spaced 50mm apart. That's the standard on Tubus, etc racks but some older Nittos just have one.
