The best bike lights are a cycling essential, whether you're commuting through city streets or blazing trails after dark.

There's a wide array of lights to choose from, with options ranging from budget-friendly urban blinkers to car-headlight-style bright beasts.

We tested dozens to help you choose the best lights for visibility, battery life, and budget.

Knog 's brightest bike light set is available as a pair or sold individually.

The Blinder 1300 (yes, that's 1,300 lumens) comes with a handlebar mount and a GoPro undermount for versatility.

The rear light has a simple clip, rather than a separate mount, with a choice of three rugged rubber bands.

Each light offers four modes, with two levels of solid light and two flashing.

The light is fairly bright ( two levels of fixed brightness, two flash patterns, one disruptive) with excellent side visibility.

To use, you either pair with a Garmin bike computer, or sync to your smartphone via the Garmin app.

The Varia ’s accelerometer can automatically detect a collision and saves clear footage from before, during, and after the incident.
