I have had one of these (in red) on the back of my helmet for years now

The original one was a different brand, it just died so I bought a few more, they're obviously made somewhere overseas and branded to spec. Not the perfect taillight, but the elastic loop happens to work well with my helmet and it's nicely bright. Compliments the under-seat light, and always good to have a backup.
