What is the best way to secure my rear bicycle light?

I recently purchased a new electric bicycle rear light but I'm not sure how to properly secure it on my bike. The instructions say to use zip ties, but I'm worried they may break or slip off while riding. Any tips for a more secure solution? Thanks!

In my experience, using a combination of zip ties and rubber bands can provide a more secure hold for your rear light. Start by using the zip ties to attach the light to your bike, but then add a rubber band over the zip ties for extra grip and to prevent them from breaking. This has worked great for me on bumpy rides and in wet conditions.
