One tester told of Supernova sending them out a replacement light as they toured through Azerbaijan!

Supernova E3 Pro 2 Dynamo Front Light

This is about as good as it gets. A well-built, rebuildable unit with a long warranty and near-perfect beam pattern and performance for road use. You’ll never have to worry about where your lights are, or whether they’re charged, ever again.

Supernova E3 Pro 2 Bike Light Review [German]

Although the Supernova E3 Pro 2 doesn’t quite get a very good rating in the test, it’s still a good choice. The “made in Germany” seal alone guarantees quality construction.

My Audax Dynamo Light Setup

When you’re on a big ride at night, you’ve got a lot of hours of darkness and sometimes battery lights won’t last long enough, so I got myself a dynamo. It’s 1 year old, it’s done six to seven thousand miles. I don’t think it’s completely watertight, but it still works.

Dynamo Powered – Supernova E3 Pro 2 Headlight

This is a standard M5 mount which means that you’re actually going to be able to mount this to just about anything and you can adjust the multimount to be able to work with a whole bunch of different setups.
