We've had many past discussions about lights, and a couple specifically about rack lights. My RSP racklight has never worked reliably.
I foolishly re-attached it to the folder this year, but it has again stopped working. Pretty sure its to do with moisture leaking in.
Any advice on a cheap replacement?
We also need a rearlight for the circe helios as we've managed to kill another rear USB stretchy light from EBC, and no longer use the childseat, which had a rearlight attached.
