## Description

The newer flat, thin toplight tail light. This on runs on batteries (included). The mounting holes are 50mm apart so it will mount easily to many rear racks. It will work with the Salsa Wanderlust racks as well or any rear rack with horizontal dual holes. A small light this one, but the the light from two LEDs is spread into a line across the width of the light, providing increased surface area for the light, and making it more visible at a distance. Three Postion switch - on/off/Senso. The Senso position enables the light and motion sensors in the taillight. When the bike is moving and it's dark, the light is automatically switched "On". When you stop, the light stays on for a few minutes, and as long as you don't move again, it switches off and stays off.

    Improvements over the B&M 4D Toplight Senso
  

*by A***L on Reviewed in the United States on June 24, 2015*

This model replaced a damaged 
  
4D Toplight Senso







  
  
     and it's immediately obvious how much more secure the design is—there’s an optional Torx T20 bolt used to secure the battery compartment to an internal metal nut rather than the 4D's wood screw through plastic, it's rated the same for battery life with one AA battery instead of two and is just as bright, and the mode select button is more reliable while the 4D's switch got permanently stuck in the first few months. Bit strange that the optional Torx bolt requires that you first drill a hole through the battery compartment cover, but not really a problem. The 4D required drilling two holes in order to mount it to the rack while this drilling is apparently optional, so that's actually an improvement. I'd recommend using the optional Torx bolt so you're sure the battery cover isn't going anywhere.Note: The slightly larger-diameter, rechargeable 
  
Imedion 2400mAh AA batteries







  
  
     fit with no problem. Purchased in 2011, they've all been cycled dozens of times and currently average 2240mAh—or >98% of their original average 2280mAh charge—with a

     charger. I mention this because they're still the highest capacity LSD (low self-discharge) batteries I'm aware of and keep this light going longer than its rated 40 hours.

    Lovely, surprisingly bright permanent light. This fit perfectly ...
  

*by B***Y on Reviewed in the United States on July 21, 2018*

Lovely, surprisingly bright permanent light.  This fit perfectly on to my Tubus Cosmo rear rack.  The switch is a bit finicky, but this rear light offers surprising visibility.  It does not flash, it is a solid light.

    Love it. Does not blink
  

*by L***N on Reviewed in the United States on January 19, 2015*

Love it. Does not blink, so if you want a light that blinks, get a different light. This is a german light, so  is constant on and does not blink. It is quite bright and I like it.
