Rear light for thule ridelong child seat

[Schneil]

Hi all

My old hybrid has been relegated to child transport duties and has a frame mounted Thule Ridealong seat fixed to it.
I'm trying to work out how to attach a rear light to my bike, as my trusty cateye was formerly mounted to a rack, which was removed to fit the child seat.

Thule do an official rear light called the Delight, which is £35 and seems a bit dear. Looking at the instructions, it's bracket glues to the seat and then the light clips on and off that.

Has anyone found a method to mount a cateye light on the Thule seat? Or shall I just go oldskool and mount a light on one of the seatstays?

Here's the seat on the bike - as you can see it's hefty!

Decathlon do a range of USB lights with a self adhesive mount.

If you dont remove the seat why not just use one of the generic O-ring mounted one's fixed on the blue handle on the back of it.
