Battery-powered lights for bicycles have undergone significant development in recent years - not only in terms of brightness, but above all in terms of efficiency. LED technology is now standard: all manufacturers use white LEDs, which produce a lot of light from little power. However, it is not just the brightness of the light source that is decisive, but also the duration of the light so that the luminaires do not have to be constantly plugged in. Modern control systems regulate the light intensity dynamically and ensure that there is still sufficient light on the road even when the battery charge is running low, so that the evening drive does not end abruptly. The lighting times of the tested systems varied between just under two hours and a solid six hours; the charging time to replenish the battery is between two and five hours, depending on the model and capacity. In our selection of podium candidates, we weighted the headlights more heavily than the rear light.
Front light with high beam is one of the best on the market. The headlight illuminates the road, including the edge of the road, brightly and homogeneously, even with low beam. Switching works practically via a radio switch that can be attached anywhere on the handlebars. The headlight achieves a light duration of over three and a half hours at the highest light level; this can be extended using the app connected to the smartphone. The standard holder fits round handlebar cross-sections, alternatives for integrated cockpits are available as accessories. The rear light has an integrated brake light and is mounted on the saddle frame using a magnetic holder.
The Supernova Lights headlight is technically on a par with the Lupine, but is slightly larger. The high and low beam is operated via a test switch with cable connection; there is also an app for controlling the brightness, which is somewhat clearer than that of the competitor. The illumination of the high and low beam is excellent, the light duration at the highest light level is good. The headlight is mounted on the handlebars using a bracket, alternative brackets are available. At the time of testing at the end of 2025, Supernova did not yet have a retrofit rear light, but according to the manufacturer, this should be on the market in 2026.
For a set price of 150 euros, Busch & Müller offers a solid package of Headlights and Rear light. We liked the workmanship, as well as the intuitive operation with a push button and the reliable battery status indicators. The illumination of the road is good, as is the three-hour light duration at the brightest level; the rear light even shines for 24 hours on a single charge. The headlight bracket only fits on round handlebars, but a bracket with Go Pro standard for mounting on the boom is also available as an accessory.
