This part makes it possible to attach the rear light of your bike, which is normally mounted on the seat post, directly to the seat. Especially if you use a dropper seat post, this part is extremely helpful because the light can move up and down with it. This increases visibility for other road users.
The whole thing is mounted with 2 M4 countersunk screws and M4 hexagon nuts.
The author marked this model as their own original creation.
