Femto Drive Rear Light

A perfect match for the Lezyne Femto Front Light, the Femto Rear Light looks just like its sibling but sports a red lens and puts out 7 lumens instead of 15.

The Femto Drive Rear Light's durable CNC-machined aluminum body is weather-resistant, dissipates heat to protect the batteries, and won't rust no matter how long you leave it outside. The Femto's red lens doubles as its on/off button for a super-clean, button-free look. You can use the lens to cycle through four flash modes and one steady mode, as well.

The Composite Matrix back plate can be unscrewed to replace the two CR2032 disposable batteries, and the multi-position silicon-rubber strap can be moved to angle the light side-to-side or straight back. The Femto provides 7 lumens of light to make you more visible in traffic. The batteries provide 30 hours of burn time in steady mode and 60 in flash.

The Lezyne Femto Rear Light is available in Black, Blue, Silver, or Red and is compatible with just about any bicycle seatpost.

Nice simple light

Familiarity:: I've used it several times

This is a nice simple light that is powered by a replaceable battery. I saw the other review that complained about the light pointing down and thought I could live with that. When I first put it on, it did point down. I took it off to do some maintenance and noticed a subtle bevel in the mounting surface. Flipping the light over made it level on when mounted on a seat post. So yes, this does work on a seat post but the correct orientation is not obvious.
