Supernova Airstream Tail Light 2 – Seat Post, Black
The Supernova Airstream Tail Light 2 – seat post version (KA616-BLK) – is a tail light without its own battery: it draws its power from the Airstream 2 front light. Charge the front light and both lights are ready.

Why this tail light?
Powered by the front light. It runs from the Airstream 2 battery – no extra charger, no extra battery, nothing to forget.
Never runs flat on its own. Small battery tail lights tend to die when you need them most. This one is on whenever the Airstream 2 is on.
Aluminium housing. Anodized aluminium, matching the Airstream 2 front light.
5-year guarantee. Backed by Supernova with at least 10 years of repairability.

Mounted on the seat post
The light sits on the seat post and is held by the included O-ring – a good choice for bikes without a rack.
The cable is 1,200 mm long and cannot be shortened, so plan the route along the frame to the front light before fitting.
Who is it for?
- Airstream 2 owners. A matching, always-on rear light that needs no charging of its own.
- Bikes without a rack. Road, gravel and city bikes where the seat post is the natural place for a rear light.
- Riders who hate charging. One battery for front and rear.

Frequently asked questions
Does the Airstream Tail Light 2 work with other front lights?
It is made for the Supernova Airstream 2 front light, which supplies its power.
Does it have its own battery?
No. It is powered by the front light, so it is only on when the Airstream 2 is on.
Seat post or rack version – which do I need?
The seat post version mounts with an O-ring on the seat post. If your bike has a rack with 50 mm hole spacing, the rack version is the cleaner choice.
