[Closed] Does anyone use Fizik Blink ICS Rear LED Bike Light

No idea what it's called, but if you mean one of those that slots into the back of the saddle, I use one. Seems OK but I only use it as a backup/emergency for one of those fibre flare thingummies.

Edit: Just looked it up, yes that's what I've got.

The former. Better than nothing, and a good idea but too weedy really.

they work fine until the bloody thing gets covered in mud & then the thing plays up, becoming tempermental ! even when cleaned after every ride with a toothbrush to remove the mud/grit it still would switch itself on & drain the battery ! i had three of these which after a few weeks riding, all suffered the same problem, so ended up IN THE BIN !
