Toplight Flat S Senso [Battery Light]

Busch & Müller's Flat S Senso light uses Line Tech reflectors that very efficiently reflect the center LED light out in a vertical line.
The switch modes are ON/OFF/SENSO. On and off are obvious enough. Senso Mode sets up the light to detect a combination of motion and lightness. If the light goes into motion AND it is dark out, the light turns on. If motion stops for a stretch of time, then the light will automatically turn off.
50mm & 80mm rack/bracket spacing.

- The Flat S Senso is the nicest battery style light that replace the reflector on Brompton Bikes. This is a simple way to upgrade your Brompton lighting game without going all out with a dynamo kit.
- This light is a great rear light to add to a Tubus Rack, or any rack with 50/80mm spacing (a common euro spec, but not so much for american racks).
- NOTE:When using this light on the Brompton Rack you will need to remove the two top bolts on the rack for battery installation and replacement.
