SON Rear Light - Seatpost Mount - Black / Red

I recommend this product

Does the job and pretty bright. Wish there was a flashing version (non German regulation compliant).
Crimping and heat shrinking the connectors to hook up to edelux II front light was straight forward and managed to internally route the cable. Also added some solder to the crimped connectors for a better contact and to add durability.
Wish that the cable could be disconnected at the rear to make internal routing a more practical and flexible option allowing the light to be more easily disconnected an demounted.
Got the larger wire so I could mount it on the seat tube instead of the seat post which works well and gives a lower position so it's still visible with a bikepacking seatpack mounted.
If doing lots of night riding I would add a battery powered rear light with a flash mode for UK riding for a bit better visibility and peace of mind.

Moderately straightforward to fit after watching a video and reading the instructions, but applying the shrink wrapping to to protect the cable connections is a pain to get right. not sure there is anything which could be done to make that easier though. The fit is very secure on my bike and the finish is brilliant. The light is impressively bright and has a capacitor fitted to give a stand light after a few rotations of the dynamo.

I chose this rear light on recommendation after sending a message to customer services. I got back a very helpful reply sent with little delay.

Thanks for your help!
