no Light – Rear – B&M Toplight Line Permanent Rack-mount

Important: You need this adapter to make these work on your single-hole Nitto rear racks. These lights have two bolts spaced 50mm apart. That’s the standard on Tubus, etc racks. Some Nittos just have one.

Busch & Muller’s top-of-the-line light called “TopLight Line permanent”. This is maybe the best battery powered rack mount tail light you can buy right now. We have the dyno powered version too. The “Line” technology is tough to explain but this picture should help:

So 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.

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!

They have cheaper versions but we won’t stock them. As with all our Euro light products the instructions are in German but it’s all simple to understand.

Comes with a single AA battery, which is all you need. The battery compartment snaps open, but you have the option to thief-proof it with a torx screw which is included along with a tool. You don’t have to do that though.
