I'm looking for a cheapish tail light to add a little extra visibility. I'm riding during the day, primarily morning and evening--I'm home well before dark. I had a Nite Rider TL 5.0 until yesterday . My criteria are: must be less than $30, ideally less than $25, and it must have a clip mount, as there's not a lot of my seat post visible with my giant bag there.

Thanks in advance!
