Modular Tail Light

One light that isn't stuck being one light. The 129mm bar runs across your seatpost as a single unit, or pulls apart into three — spread them where you want them, run one, run all three. Thirty amber LEDs and eight red, thirty lumens, and five modes you cycle from a remote on the bars without reaching back or looking down.

Amber steady, red steady, all flash, left, right. The 600mAh battery runs about five hours and charges over USB — red while it's charging, green when it's done, no guessing. The whole thing including the remote weighs about as much as a chocolate bar.

Function you need. Style you choose. Ride sorted.
