With the new job I tend to do my bicycle runs much later, usually after dusk or at night. That time of day has its own special challenges: occasionally I get mobbed by bats and flying foxes, one of the trails is full of frogs or toads if I'm really late, and oh, there are lots of homo sapiens automobilis who are blind as bats.

Since the number of the damn saps who pass me much too close is a lot higher at night I decided to replace my dinky red flasher with a Really Annoying Red Light.

So I spent the grand sum of $22 on a set of "Tioga Dual Eyes", and the better light seems to help - it's really bright and obnoxious, might not be good for epileptics but that's SEP. Very much recommended.
