As cycling safety becomes a top priority for riders across the US, the introduction of adaptive lighting technology like the Knog Cobber Reflex Lights could significantly enhance visibility and awareness on the road, especially in urban environments. This innovation raises important questions about how cyclists can better equip themselves for safety while riding in varying conditions.
Knog has been around for ages, but it seems like lately they’re really coming back strong. Knog’s latest lights add Adaptive Reflex technology to their already impressive Cobber series (which were launched back in 2017), which delivers an exceptionally wide 330º beam angle. Knog is calling them “smart lights for analog bikes,” though you could totally run these on your ebike, too.

Now, they automatically dim or brighten based on how bright it is out, how fast you’re going, and how far you’re leaning your bike. That latter one? It’s mostly for the rear, changing the strobe effect to animate a right or left turn, acting like a quasi-turn signal.

Otherwise, the lights get brighter as you speed up or head into a dark tunnel (or, you know, you ride at night). You can customize the modes via their web app (and save the profiles like ‘commuting’, ‘training’, etc.) or just rely on the four standard modes. Output varies by model, and here are your options:
| FRONT | REAR | |||
| MODE | LUMENS | RUNTIME | LUMENS | RUNTIME |
| High | 150 | 2.5 hr | 75 | 2.5 hr |
| Low | 50 | 8 hr | 20 | 8 hr |
| Hype | 350 | 8 hr | 250 | 8 hr |
| Eco | 40 | 40 hr | 20 | 70 hr |
