The Tailcast light, the wireless remote, the seatpost mount and base, silicone straps, a USB-C charging cable and a user manual.

The mount attaches to the back of your seatpost, just under the saddle. The light clicks into the mount and pops off in a second when you want to charge it or take it with you. The remote straps to your handlebar with a silicone band.

Press left or right on the remote. The arrow on that end of the light blinks amber, and a bold amber arrow is projected on the road beside your rear wheel, blinking in time.

Five: steady red, flashing red, hazard (both arrows flash, on the light and on the road), left turn and right turn.

The arrows are brightest from dusk onward, which is when drivers need them most. In bright sun they're faint.

With the USB-C cable in the box. The light has a 1200 mAh battery.

It's made for everyday riding, so light rain and road spray are fine. Don't submerge it or point a pressure washer at it.

The seatpost mount straps around round seatposts and the remote straps around round handlebars, so it fits most road, gravel, hybrid and commuter bikes. Not sure? Email support@mytailcast.com with a photo of your bike.
