I think my husband is pretty clever.
A few years ago, he rigged up a diffuser for my rear bicycle light, to help make my bike more visible from the side. The diffuser has been such a success I’m quite used to getting compliments on it whenever I ride at night.
The diffuser itself is quite easy to make, so I’ve written up an Instructable on how to do it. You might like to make your own visible, disco bike light too 🙂
