Lumos Firefly 2 light bundle with handlebar end mounts, regular handlebar or seatpost mounts, and charging cradle. These can function as turn signals, front and rear lights, or in conjunction with a Lumos helmet and/or phone app. These are brand new - I won them last week in a bike to work day raffle at a local bike shop, but they are just too much tech for me. although they are completely new, the handlebar end mounts are discolored, so please consider that.

They currently sell for $109.95 on Amazon for this same bundle minus the handlebar end mounts, and 139.99 at the bike shop.
